[R] argument "string" is missing, with no default

[Shivi Bhatia]

Hi All,

I am trying to fetch data from a pdf file with the below code but getting
the error message:
Error in stri_split_regex(string, pattern, n = n, simplify = simplify,  :
  argument "string" is missing, with no default

library(readr)library(stringr)library(magrittr)library(dplyr)
table_data <- nvsr65_05[ [ 14 ] ] %>%
  str_split(pattern = "\n") %>%
  unlist() %>%
  str_subset(pattern = "^[^…].*(\\. ){5}") %>%
  str_c(collapse = "\n") %>%
  read_table(col_names = FALSE) %>%
  mutate(X2 = str_replace_all(X2, "(\\. )*", ""),
 X5 = rep(c("Neonatal", "Postnatal"), each = 10)) %>%
  set_names(value = c("rank", "cause_of_death", "deaths", "percent", "group"))

Please advice. Thank you.

Hi

the output seems to me rather weird. Unles you have NaNs in input data frame 
you should not get NaN as a result.

Anyway, your aggregate will give you NA or NaN even when there is only one NA 
or NaN in your input data frame. So I suggest to use

sentiments_per_Category <- aggregate(relative_sentiment_frequencies,            
                          by = list(Category = df$Case.Category), mean, 
na.rm=TRUE)

This should strip all NAs before calculating mean in each category.

Complete cases removes all lines with at least one NA in your data frame, which 
probably results to empty data frame.

Cheers

[R] NaN in Scoring Sentiment

[Shivi Bhatia]

Hi All- I am running a sentiment scoring model and the code is as below:
sentiments_per_Category <- aggregate(relative_sentiment_frequencies,
 by = list(Category =
df$Case.Category), mean)

while i run the head command most of the values are NaN. i then used
complete.cases on my data frame
df[complete.cases(df),]
 but it does not seems to work. Please advice if there is a way to handle
NaN.

Dear Shivi

You are running R 3.5.1 according to your session info. Why are you 
installing a version for R 3.3? Note that the up-to-date version depends 
on R > 3.4.0 so it is no surprise that you get problems.

Hi Michael,

I was able to install RGtk2 from install.packages("
https://cran.r-project.org/bin/windows/contrib/3.3/RGtk2_2.20.31.zip;,
repos=NULL) but after installing this and trying to install rattle i get
this error:
Error : package 'RGtk2' was installed by an R version with different
internals; it needs to be reinstalled for use with this R version
ERROR: lazy loading failed for package 'rattle'

I tried installing rattle from install.packages("rattle", repos="

Hi,

Need assistance on installing Rattle.

I have followed the instructions on https://rattle.togaware.com/
but still facing error installing the package.
ERROR: dependency 'RGtk2' is not available for package 'rattle'.

Re: [R] length of 'dimnames' [2] not equal to array extent- For Correlation Plot

[Shivi Bhatia]

Hi Sarah,
Thank you for your help.

I tried using CR1<-as.matrix(CR1) but gives error Error in corrplot(CR1,
method = "circle") : The matrix is not in [-1, 1]!. I am using a corrplot
library.

Please find the reproducible example:
dput(head(CR1,10))
structure(c(26L, 46L, 39L, 38L, 47L, 59L, 56L, 61L, 43L, 60L,
78L, 63L, 2L, 58L, 8L, 1L, 1L, 9L, 11L, 2L, 1037500L, 46747L,
346300L, 672000L, 729000L, 470800L, 423000L, 72184L, 368022L,
1037500L), .Dim = c(10L, 3L), .Dimnames = list(NULL, c("AGE",
"OLD_CAR_PURCHASE_YRS", "Total.Spend.With.Maruti")))

Please advice if this would help.

Thank you. Shivi

[R] length of 'dimnames' [2] not equal to array extent- For Correlation Plot

[Shivi Bhatia]

Created a new data set with 3 numeric variable to find correlation

CR1<- mar%>%  as_data_frame%>%  select(AGE, OLD_CAR_PURCHASE_YRS,
Total.Spend.With.AA)

had to convert it to a data frame, code:

as.matrix(as.data.frame(CR1))

Now i need to run a correlation plot for these 3 variables:

corrplot(CR1, method = "circle")

But i am getting this error:
Error in matrix(unlist(value, recursive = FALSE, use.names = FALSE), nrow =
nr, : length of 'dimnames' [2] not equal to array extent
Researched and found Correlation
that
corrplot requires a matrix however the error is still the same.

[R] arguments imply differing number of rows

[Shivi Bhatia]

Hi Team,

I using the syntax as:

data.df<- data.frame(
  city= c(rep(c("Delhi", "Bangalore","Chandigarh"),each=5)),
  population= c(4000:6000,3500:4300,3000:3200)
)

But i am getting the error as arguments imply differing number of rows: 15,
3003.

Tried searching google but could not understand & find the solution.

Thanks, Shivi

Re: [R] R and Tableau Compatibility

 blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px 
#715FFA solid !important; padding-left:1ex !important; background-color:white

connect to R studio you have to write your scripts in R and then call those in 
tableau.

Not sure what you are expecting. When I go to the Tableau website and search 
their "Support" links I almost immediately find:

https://www.tableau.com/search#q=r=support

Following a link with the word "configuring" I see:

http://kb.tableau.com/articles/HowTo/configuring-tableau-server-for-r-and-rserve

 which says to use the current version of R. Since you are using a 
closed-source, commercial product., you really should be asking this question 
on their support portal.

[R] Error in .jcall

[Shivi Bhatia]

Hi Team,
I am creating an n-gram analysis on a text mining data however receving the
error as:-

Error in .jcall("RWekaInterfaces", "[S", "tokenize", .jcast(tokenizer,  :
  java.lang.NullPointerException

I have used the function:
Ngramtok= function(x)NGramTokenizer(x, Weka_control(min=1, max=5))
 and then using this as below:-

ngram1= DocumentTermMatrix(cnt_reason,control = list(tokenize= Ngramtok)).

Checked stack overflow for the error here -
http://stackoverflow.com/questions/38605088/creating-ngrams-in-r where it
was advised to remove the blank rows but it did not help.

I have strangely used this earlier but it now not working now.

Please suggest.

[R] Reading Multiple Files for Text Mining in R Using TM Package?

[Shivi Bhatia]

Hi All ,

I am trying to read few csv files for some text mining assignment.

I have used this command to check the # of files in the working directory:

length(dir(path="D:/Shivi/R Project", all.files = TRUE))
This results to more than 220 approx.

I just need 3 files from these to use for the text mining purpose however
if i use:

docs<- Corpus(DirSource(directory = "D:/Shivi/R Project"))
this reads all the 220+ files

Please suggest how to achieve this feat. Have researched on stack overflow,
where they have used multiple read.csv statements to read multiple files
however do not find that very effective way.

Thank you.

[R] Error in FUN(content(x), ...) : invalid input in 'utf8towcs' in Twitter Analysis using TM package

[Shivi Bhatia]

Hi All,
I am working on a twitter analysis using the TM package. Below are some
codes:

1- Here i am creating a data frame of the data collected from twitter
chennai=as.data.frame(cbind(tweet=jallitext,date=jallidate,lat=jallilat,lon=jallilon,
 isretweet=isretweet,retweeted=retweeted,
retweetcount=retweetcount,favorite=favoritesCount,
 favorited=favorited))

2- corpus<- Corpus(VectorSource(chennai$tweet)) The output gives me:
Metadata:  corpus specific: 0, document level (indexed): 0
Content:  documents: 6000

However while changing the text to lower using the tm package i get this
error:

Error in FUN(content(x), ...) :
  invalid input 'RT @Aariactor: Officially #jallikattu protest is over
yesterday we won í ½í²ªí ¼í¿» thx to government í ½í¹ í ¼í¿»' in
'utf8towcs'.

After researching a lot i am using this code:-
tryTolower = function(x)
{
  # create missing value
  # this is where the returned value will be
  y = NA

This makes the tweets case sensitive but  when i create a document term
matrix i get this error:

Jalli<- DocumentTermMatrix(corpus)
Error in UseMethod("TermDocumentMatrix", x) :
  no applicable method for 'TermDocumentMatrix' applied to an object of

Request you to please assist with this error. Thank you.

[R] PNG File in R Markdown HTML

[Shivi Bhatia]

Hi Team,

I am successfully able to add the company logo to the R markdown file using
the code below:

```{r, fig.width=3, fig.height=15,echo=FALSE, warning=FALSE, message=FALSE}
library(png)
library(grid)
img <- readPNG("D:/Shivi/R Project/Name.png")
 grid.raster(img)
```
However the image gets displayed at the bottom of the html page. I have
tried deleting any empty space after this code but it does not help.

Request you to please advice.
Thanks, Shivi

[Shivi Bhatia]

These are the packages i am using:
library(woe)  #WEIGHT OF EVIDENCE
library(InformationValue)  #INFORMATION VALUE

The syntax used is :
WOE(X=SFDC1$log_caseage, Y=SFDC1$survey)
WOETable(X=SFDC1$case_age, Y=SFDC1$survey)
IV(X=SFDC1$case_age, Y=SFDC1$survey)

Hi Mark,

It gives me num [1:5083]. I have used head also to see first 10 obs:

head(SFDC$case_age,10)
 [1] 24.84  0.05 13.38  0.15 11.11  4.16  8.13  0.07  3.61  0.00

Thanks.

[R] 0 rows> (or 0-length row.names)

[Shivi Bhatia]

I know this question has been asked zillion times but even after consulting
Stack Overflow & other forum cant figure out the reason.

I have one var in my data-set names case age. This variable is numeric as:

class(SFDC$case_age)

*numeric*

however it throws this error:

<0 rows> (or 0-length row.names)
As checked this only happens either there is some space at the end of the
variable name, or there are no values whereas this is a numeric variable
with no missing values and has a total of 5400 observations.

This var has a range from 0 to 240 in number of days for case variable
hence i need to do a logarithm transformation & make it use in the model.
Total unique obs are around 1500.

Please advice.

Re: [R] Error in riv package

[Shivi Bhatia]

Hi Ista, Thanks for your reply.

I had added a detailed explanation on this one & researched before asking.
May be someone did not read it i cant do much though David's explanation
helped as why it wasnt able to run the syntax.

Please see trail mail: (though i have already moved ahead and taken an
alternate package to calculate IV for each var at a time):


HI Team,
I am working to reduce the # of predictor variables from the model using woe
and iv values. For this i am using riv package. However i am
having a hard time installing this package:
install_github("riv","tomasgreif")
install.packages("DBI",dependencies=TRUE)
The error i receive is :
*Username parameter is deprecated. Please use tomasgreif/riv

and THEN this part:

The other approach i have to use the library(InformationValue). I have this  as
below:
 WOE(X=SFDC1$support_cat, Y=SFDC1$survey)
 WOETable(X=SFDC1$support_cat, Y=SFDC1$survey)
IV(X=SFDC1$support_cat, Y=SFDC1$survey)

This package assists me achieve what i am looking for but here i need to add
one independent variable at a time to see whether it is
predictive or not. Is there a way i can add all variables at a go or have
to add one by one,
For the above package (riv) i have seen an example which helps to take
the entire
data range and  predictive the power of each predictor. The
link for the same is:

information-value-in-woe-package/

Re: [R] Error in riv package

[Shivi Bhatia]

Hi David,

If this has loaded correctly then it still does not allow me to run
iv.multi command where a can add all the variables in the model and find
their respective WOE and IV values.

Thanks, Shivi

[R] Error in riv package

woe and iv values. For this i am using riv package. However i am having a
hard time installing this package:

as below:
WOE(X=SFDC1$support_cat, Y=SFDC1$survey)

This package assists me achieve what i am looking for but here i need to

Hi Michael,

In all the masking process some of the variables were missed. Please find
the updated file.

Also here is the updated code: (i am removed one of the var as it had
missing information):

glm.fit= glm(survey ~ support_cat + region+ support_lvl+ skill_group+
application_area+ functional_area+
  repS+ case_age+ case_status+ severity_level+
  sla_status, data = new, family = binomial)

Kindly assist with the same.

Re: [R] glm.fit: fitted probabilities numerically 0 or 1 occurred & glm.fit: algorithm did not converge

[Shivi Bhatia]

Hi Michael,

There is no output as the model does not generate any coefficients and
simply throws this error.

I hope you are not asking for a reproducible example.

[R] glm.fit: fitted probabilities numerically 0 or 1 occurred & glm.fit: algorithm did not converge

[Shivi Bhatia]

Hi Team,

I am creating *my first* Logistic regression on R Studio. I am working on a
C-SAT data where rating (score) 0-8 is a dis-sat whereas 9-10 are SAT. As
these were in numeric form so i had as below created 2 classes:

new$survey[new$score>=0 & new$score<=8]<- 0
new$survey[new$score>=9]<- 1
This works fine however the class still shows as "numeric" and levels shows
as "NULL". Do i still need to use "as.factor" to let R know these are
categorical variables.

Also i have used the below code to run a logistic regression with all the
possible predictor variables:
glm.fit= glm(survey ~ support_cat + region+ support_lvl+ skill_group+
application_area+ functional_area+
  repS+ case_age+ case_status+ severity_level+
  sla_status+ delivery_segmentation, data = SFDC, family = binomial)

But it throws an error:-
Warning messages:
1: glm.fit: algorithm did not converge
2: glm.fit: fitted probabilities numerically 0 or 1 occurred

I checked online for the error and it says:
"glm() uses an iterative re-weighted least squares algorithm. The algorithm
hit the maximum number of allowed iterations before signalling convergence.
The default,
documented in ?glm.control is 25."

Kindly suggest on the above case and if i have to change my outcome var as
as.factor.

Thank you, Shivi

Re: [R] Creating Dummy Var in R for regression?

[Shivi Bhatia]

Thanks you all for the assistance. This really helps.

Hi Bert: While searching nabble i got to know R with factors variables
there is no need to create dummy variable. However please consider this
situation:
I am in the process of building a logistic regression model on NPS data.
The outcome variable is CE i.e. customer experience which has 3 rating so
ordinal logistic regression will be used. However most of my variables are
categorical. For instance one of the variable is agent knowledge which is a
10 point scale.

This agent knowledge is again a 3 rated scale: high medium low hence i need
to group these 10 values into 3 groups & then as you suggested i can
directly enter them in the model without creating n-1 categories.

I have worked on SAS extensively hence found this a bit confusing.

Thanks for the help.

[R] Creating Dummy Var in R for regression?

[Shivi Bhatia]

Dear Team,

I need help with the below code in R:

gender_rec<- c('Dr','Father','Mr'=1, 'Miss','MS','Mrs'=2, 3)

reasons$salutation<- gender_rec[reasons$salutation].

This code gives me the correct output but it overwrites the
reason$salutation variable. I need to create a new variable gender to
capture gender details and leave salutation as it is.

i tried the below syntax but it is converting all to 1.

reasons$gender<- ifelse(reasons$salutation== "Mr" & reasons$salutation==
"Father","Male", ifelse(reasons$salutation=="Mrs" & reasons$salutation==
"Miss","Female",1))

Please suggest.

[R] Help with the RMD Output & rCharts Package

[Shivi Bhatia]

Dear Team,

I am in need of urgent help on RMD output in html.

A) I am working on a sentiment analysis problem and have built a sentiment
model which works perfectly on R Studio however the same on the RMD shows
all the processing steps and details.

I have used echo= FALSE but i still the see the output as below:
Loading required package: stringr
Attaching package: 'stringr'
The following object is masked from 'package:qdap':
The following object is masked from 'package:igraph':%>%

B) i am also using rcharts to create charts on the above but as mentioned
above i dont see output in RMD whereas i see the output in R studio. The
code for the same is"
p4 <- nPlot(~ score, data = abc.sentiments, type = 'pieChart')
p4$chart(donut = TRUE)
p4


Please let me know if i need to share the sentiment code in a text file.

[R] WordCloud Does not display in RMD File in R Studio

[Shivi Bhatia]

Dear Team,

I have created a text mining solution for one of my business owners.

I am sharing with his using RMD via HTML. All is working ok however the
WordCloud does not populate any output in RMD file.

Few months back when this happened on R studio i searched and used
dev.off() to shut down any concurrent running session but this also does
not help.

Other plots that i have created such ggplot and barpplot they are being
displayed. similarly i can show wordcloud also in R Studio but not on RMD.

Not sure what i am doing wrong as i only get a message staing NULL when i
run wordcloud.
Plz find the code for wordcloud if that helps:
word0<- names(frequency)
png("p3_sa_para.png", 640, 480)


wordcloud(word0,frequency,random.order =F,
colors = brewer.pal(8, "Dark2"),scale = c(5.5,0.5),min.freq = 100,
max.words = Inf)

Re: [R] Date Time in R

[Shivi Bhatia]

These are some of the codes will i have
eir$date<- as.Date(eir$date, "%d-%m-%Y")
class(eir$date)
eir$week<- (eir$date)
eir$week<- weekdays(as.Date(eir$week))
eir$week<- as.factor(eir$week)

Re: [R] Date Time in R

[Shivi Bhatia]

Thanks Tom for the recommendation. This is now working.

Apologies if this sounds like a juvenile but i am not very good with dates
in R. What i initially did when i saw date as factor and then tried
converting with lot many transformation that is where it went bad.

But thanks to all this is really what i wanted.

 Factor w/ 32 levels "05-30-16","05-31-16",..: 1 1 1

head(a1$date)
05-30-16 05-30-16 05-30-16 05-30-16 05-30-16 05-30-16
32 Levels: 05-30-16 05-31-16 06-01-16 06-02-16 06-03-16 06-04-16 06-05-16

Re: [R] Date Time in R

[Shivi Bhatia]

Hi David please see the code and some reproducible data:
eir$date<- as.Date(eir$date,format = "%m-%d-%y")  then i had used the
lubridate library to help with the dates:
install.packages("lubridate")
library(lubridate)
eir$date <- mdy(eir$date)
weekdays <- wdy(eir$date)
week names <- wdy(eir$date, label = TRUE)

This the output from the file:

structure(list(date = structure(c(NA_real_, NA_real_, NA_real_), class =
"Date"),

month = structure(c(2L, 2L, 2L), .Label = c("Jun","May"), class = "factor"),

day = c(30L, 30L, 30L),

weekday = structure(c(2L,2L, 2L), .Label = c("Fri", "Mon", "Sat", "Sun",
"Thu", "Tue","Wed"), class = "factor"),

survey_rating = c(3L, 2L, 3L), query_status = c("Yes", "Don't know","No"),

 a = c("05-30-16", "05-30-16", "05-30-16")), .Names = c("date","month",
"day", "weekday", "survey_rating"), row.names = c(NA, 3L), class =
"data.frame")

There are several other variables that i have removed which are not
relevant in this context.

Re: [R] Date Time in R

[Shivi Bhatia]

Thanks Marc for the help. this really helps.
I think there is some issue with the data saved in csv format for this
variable as when i checked:
str(eir$date)- this results in :-
Date[1:5327], format: NA NA NA NA NA.

Thanks again.

Re: [R] Date Time in R

[Shivi Bhatia]

Hello Again,

While i tried your solution as you suggested above it seems to be working.
Here is the output
temp<- dput(head(eir$date))
c("05-30-16", "05-30-16", "05-30-16", "05-30-16", "05-30-16", "05-30-16")
however it still shows class(eir$date) as character and hence i cannot find
weekdays from this variable.

Sorry but i still dont understand in totality how R reads dates even though
have tried enough.

Regards, Shivi

Thanks Duncan for the quick response. I will check again as you suggested.
If that doesn't work i will share a reproducible example.

Thanks again

[R] Date Time in R

[Shivi Bhatia]

Hi Team,

This scenario may have come across a number of times however i checked
nabble & SO and couldn't find a solution hence request assistance.

I have a date variable in my data-set eir. The class of this var was
character while i had read the file in r studio. Example of date - 05-30-16

To change this i have used eir$date<- as.Date(eir$date, "%m-%d-%y"). This
converts it to a date variable. However when i check few obs
with head(eir$date) all the results are .
I also need to create weekdays from this date variable but until i get this
resolved i cant find a weekday. For weekday i have used:
eir$week<- (eir$date)
eir$week<- weekdays(as.Date(eir$week))
class(eir$week)
eir$week<- as.factor(eir$week)
head(eir$week)

Head of this eir$week results again as expected in  but shows Levels:
Friday Monday Saturday Sunday Thursday Tuesday Wednesday

Not sure what i should do here. Kindly suggest.

[R] findAssocs in TM package in R help?

[Shivi Bhatia]

Good Day,

I am working on a text mining assignment and have built the document matrix
using the tm package.

Now I need to run findAssocs from my dtm with some word say 'like' with a
correlation of 0.70 but  as far as i have been researching it tells it this
function is only viable when we have more than 1 doc however in my case i
only have 1. So please suggest if there is an alternate to this issue.

This is because there are words that correlate to each other in the data I
am dealing with.

Kindly advice.

[R] 'ref' must be an existing level

[Shivi Bhatia]

Dear Team,

I am running a multinomial logistic regression model for one of the
fictitious data before i implement the same on my real data.
Here i am trying to predict based some scores and economic group whether a
person will go for a diploma, general or honors.

The code below:
m11$prog2<- relevel(m11$prog, ref = "honors"

already loaded the nnet library. However i got the below error:
Error in relevel.factor(m11$prog, ref = "honors") :
  'ref' must be an existing level

I have tried searching on SO and nabble but did not find an answer that
could help.

Please suggest what is incorrect. Also checked the class of the var and is
a factor variable.

I tried as suggested however with this code:

lengths of 'breaks' and 'labels' differ. Now as a result i have values

[R] Help with the Cut Function

[Shivi Bhatia]

Dear Team,

Please see the code below:

Age1<- cut(desc$Age, breaks = c(20,30,40,Inf),labels = c("Low","Mid","Top"))
here i am creating three categories as mentioned from the age var from desc
data set.
All the values are set correctly however the values which are below 20 are
set to NA.
Is there anything i am doing incorrect.

[R] Error in setwd() : argument "dir" is missing, with no default

[Shivi Bhatia]

Dear Team,

I have searched for this error at various forums but enable to find a
relevant solution.

When i had installed R studio the WD was saved at a particular location now
when i try to change it gives me this error:

Error in setwd() : argument "dir" is missing, with no default. I have tried
setting the WD using Shift+ Ctrl+ H or using setwd() command. While it
changes the WD for that particular session but when i restart the session
it is again reset to the old previous location hence every instance i have
to reset this as all my data and other files are saved at another location.
While searching at some of the forums like stat exchange it was advised to
use setwd("../") as it selects your WD one step back however with this also
i cant fix the issue.

Kindly advice at the earliest.

Thanks, Shivi

[R] Warning Message With WordCloud

[SHIVI BHATIA]

Dear Team,

 

I am working on Wordcloud package for one of my projects. While it running
fine it is not showing the top most values in the output as it should. I
have ran it earlier and it was fine but now there seems to be an issue. 

 

The wordcloud image shows the values which are appearing only once or twice.
Below is the code I have used:

 

wordcloud(nnn,freq,random.order =F,colors=brewer.pal(8,"Dark2"),

  scale = c(5.5,0.5),min.freq = 50,

  max.words = Inf) 

 

There are words which are repetitive like 1000 times but none of those
appear. Not sure where I doing it wrong have checked multiple stats exchange
forum and help in r on wordcloud. 

 

This is really urgent. I have tried installing tm package. 

 

Thanks, Shivi

[R] R Memory Issue

[SHIVI BHATIA]

Dear Team,

 

Every now and then I face some weird issues with R. For instance it would
not read my csv file or any other read.table command and once I would close
the session and reopen again it works fine. 

 

It have tried using rm(list=ls()) & gc() to free some memory and restart R


 

Also today while closing the R session it took more than 10 minutes. I am
not sure as to what is leading to this. Kindly throw some light on this. Not
sure if I have provided enough information.  

 

Thanks, Shivi

Dear Team,

 

Every now and then I face issues while connecting to Twitter:

 

Error in check_twitter_oauth() : OAuth authentication error:

This most likely means that you have incorrectly called
setup_twitter_oauth()'

 

I have checked multiple github suggestion and statsexchange forum & have
followed all suggestion such as to update httpuv package and calling out the
library names in a certain manner however I am still not successful.. Also
apart from these there was also recommendation on httr package to be called

Error in unloadNamespace(package) : 
  namespace 'httr' is imported by 'twitteR' so cannot be unloaded
 
 
Not sure on what is to be done here hence require help from the forum.

[R] Help with the Twitter Analysis

[SHIVI BHATIA]

Dear Team, 

 

Kindly refer to the error below while generating a Twitter Analysis for my
firm:

 

# Warning message:

# In doRppAPICall("search/tweets", n, params = params, retryOnRateLimit =
retryOnRateLimit,  :

 

As I checked on forums such as StackOverflow and other r related literature
it mentioned that this error happened due to the reason that there were less
tweets than what I requested for. On further investigation I got to know
that due to twitter API restrictions we can't fetch older tweets i.e. any
tweet prior to 6-7 days. This seems to be a very big hurdle for me to build
a sentiment analysis for the company as the time frame is very low. 

 

Request to please advise if there is some work around for the same or best
possible alternative. 

 

Thanks, Shivi

[R] Dput Help in R

[SHIVI BHATIA]

Dear Team, 

 

I am facing an error while performing a manipulation using a dplyr package.
In the code below, I am using mutate to build a new calculated column:

 

kp<-read.csv("collection_last.csv",header=TRUE)

mutate(kp,dif=DOC_AMOUNT-RECEIPT_AMT+TDS_AMT+REBATE)

 

However it gives an error:-

Warning messages:

1: In Ops.factor(c(28831L, 28831L, 17504L, 4184L, 36187L, 25819L, 699L,  :

  '-' not meaningful for factors

2: In Ops.factor(c(28831L, 28831L, 17504L, 4184L, 36187L, 25819L, 699L,  :

  '+' not meaningful for factors

3: In Ops.factor(c(28831L, 28831L, 17504L, 4184L, 36187L, 25819L, 699L,  :

  '+' not meaningful for factors

 

This is an error when some of my variables are factors hence I have tried to
change these to numeric so used the expression as:

kp$DOC_TYPE=as.numeric(kp$DOC_TYPE). 

 

this now shows as variable type of as "double". So expedite help on this one
i was trying to create a reproducible example and i am highly struggling to 

create one. the data i have is approx. around 1 million rows with 21 columns
hence when i use a dput option it does not capture the entire detailing and
row level info required to share and even dput(head(kp$DOC_TYPE) does not
help either. 

I have seen many stack overflow & r help column before composing this email.
Hence i need help to create this reproducible example to share with the
experts in the community. Apologies if this is a repeat.

 

PLEASE HELP AS I AM HIGHLY STRUGGLING TO BUILD ANY OUTCOME. 

Regards, Shivi

[R] Incorrect Summarization after As.numeric

[SHIVI BHATIA]

Dear Team,

 

I am working on aggregate function in R & have used the below code:

 

aggregate(a1$Final,list(Year=a1$Year),sum)

 

initially a1$Final was factor hence I used a1$Final= as.numeric(a1$Final) to
convert this into numeric. After conversion it shows the output but the
summarization from the aggregate is incorrect. This I have reconciled with
the excel pivot. 

 

Could you please suggest where could be the issue?

 

Thanks, Shivi
