Re: [R] Your browser do not suport oracle bi presentation services

[KENNETH ROY CABRERA TORRES]

Thank you José María:

You are very kind.

I will study and use your advice.

The first step, takes more information,
but not what I want. (I want the whole data set of "TRM").

I'm going to try with Selenium (RSelenium).

Thank you very much for your help.

I tried opening that URL with my browser and it worked (or at least I 
think it worked, it took me to a page where I could see a very long 
table titled "Tasa de cambio representativa del mercado (TRM)".

I tried obtaining the page using wget and I got the error you mentioned. 
When I forge wget to identify itself as Firefox, I get returned a 
different code (one that I suppose will redirect me to the page you are 
trying to scrape).

The problem could be solved by telling R to use a different user-agent, 
like Firefox or Chrome. Check 
https://stackoverflow.com/questions/4536835/changing-user-agent-string-in-a-http-request-in-r

However, I think the system that provides the HTML content you want 
relies heavily on JavaScript. You might need to end up using something 
like Selenium (https://www.r-bloggers.com/scraping-with-selenium/).

Re: [R] Can this be done in ggplot?

A very dirty solution.

I hope someone can give a better solution:

set.seed(1)
df <- expand.grid(g = factor(1:4), f = factor(c("a", "b", "c")))
df <- df[-1, ] # some factors are not present in certain groups
df$v <- runif(nrow(df))

library(dplyr)

df <- df %>% arrange(g, desc(v))
df$nv <- with(df, factor(paste(g,f)))
df$nv <- factor(df$nv, levels = df$nv)

ggplot(df, aes(x = nv , y = v, fill = f)) +
   geom_bar(position="dodge", stat = "identity")

[R] Legend symbols (line, points) in one column.

Hi David:

  - - - for the pch argument.

No, because I want a continous line for the model.
But the data as points, and in the legend to identify each one
as the example shows but in only in one column in the legend!.

 
 This is what I came up with using the panel.lmline rather than  
 building it outside the plotting function:

If the model is a linear one, it is fine, but the model could 
be a complex one that it is not programmed as panel.xxmodel, or else.

Thank you very much for your interest in finding the solution.

[R] Legend symbols (line, points) in one column.

[Kenneth Roy Cabrera Torres]

Dear R users:

I want to have in the same column both symbols, line and
points, one for a data, and the other for the model.

How can I do that?

Or is there other better form to show both data and model

of the same subject (repeated measurements on time)

data2$y-predict(model1,newdata=data2)
data2$type-rep(model,nrow(data2))
dataT-rbind(data1,data2)
dataT

require(lattice)

Re: [R] Legend symbols (line, points) in one column.

[Kenneth Roy Cabrera Torres]

It is about the legend.

As you see in the example the line is not above the points symbol.

I want the line in the symbol in the same column.

Thank you for you interest in helping me.

Have nice day!

[R] FinCenter in timeSeries with merge, cbind and rbind

Hi R users:

When I try to merge or bind (cbind or rbind) two series,
both with a FinCenter different that GMT, the
result is GMT not the original financial center?

What am I doing wrong?

##
require(timeSeries)

getRmetricsOptions(myFinCenter)
setRmetricsOptions(myFinCenter = America/Bogota)
getRmetricsOptions(myFinCenter)

fechas - format(timeCalendar(2010, sample(12, 6)))
datos - matrix(round(rnorm(6), 3))
t1 - sort(timeSeries(datos, fechas, units = A))
t1
 
fechas - format(timeCalendar(2010, sample(12, 6)))
datos - matrix(round(rnorm(6), 3))
t2 - sort(timeSeries(datos, fechas, units = B))

Re: [R] average among one factor in a nested dataframe

[Kenneth Roy Cabrera Torres]

Hi Junquian:

I try your code (there is a typo, I believe)

a-rnorm(6)
b-rnorm(9)
f1-c(x1,x2,x3)
f2-c(y1,y2)
id-c(1:6)
a_df-data.frame(cbind(id,f1,y1,a))
id-c(1:9)
b_df-data.frame(cbind(id,f1,y2,b))

But I don't understand the nested databases.
I see that both have f1 variable but I do not see f2 variable in any of
them. So, what do you mean with collapse f2?

Maybe you need to first merge() de databases and then aggregate()
them.

Have a nice day!

Re: [R] About Tinn-R

[Kenneth Roy Cabrera Torres]

Dear Marcos:

Did you try this version (version 2.3.7.1)?
http://sourceforge.net/projects/tinn-r/

Does is show the same messages?

What R version are you using?

It seems more a problem with the OS that with R or Tinn-R.

When you uninstall Tinn-R, do you check any file left in the folder:
C:/Documents and Settings/Marcos/Datos de programa/

If there are some, erase them manualy.

If the problem persist, try to rename them with different extension
like .XXX and reinstall the program.

Maybe is a problem with a bad sector in the hard disk.

Check the hard disk to see if it is the case.

Hope this helps.

 I don`t know if it is correct to make a question about R and Tinn-R in this 
 mailing-list, but I need some help with a problem for which I don't find a 
 solution anywhere.
 
 I have Tinn-R 2.3.5.2 in my notebook and I always used it with no problems, 
 until a few days ago when this signs appears everytime I start the programme:
 
 Key Violation.
 C:/Documents and Settings/Marcos/Datos de programa/Tinn-R
 Serious problem reading ini files!
 Tinn-R can not be initiated.
 Please, try to rename (or remove) the folder above and restart the program!
 
 I don't know what that means, I don`t have such folder in my notebook, and I 
 always used it normally and suddenly it doesn't work anymore.
 
 I unistalled it and installed again several times, and I tried with the 
 newest version of R and TinnR too. I can`t find help in internet, and I also 
 cleaned the registry of the computer.
 
 Thanks in advance!!

[R] Two functions as parametrs of a function.

[Kenneth Roy Cabrera Torres]

Hi R users:

I'm trying to make a function where two of the parameters are
functions, but I don't know how to put each set of parameters for
each function.

What am I missing?

I try this code:

f2-function(n=2,nsim=100,fun1=rnorm,par1=list(),fun2=rnorm,par2=list()){
force(fun1)
force(fun2)
force(n)
p1-unlist(par1)
p2-unlist(par2)
force(p1)
force(p2)
localfun1 - function() fun1(n, p1)
localfun2 - function() fun2(n, p2)
vp-replicate(nsim,t.test(localfun1(), localfun2())$p.value)
return(vp)
}

f2(fun1=rbeta,par1=list(shape1=2,shape2=2),fun2=rbeta,par2=list(shape1=1,shape2=2))

Thank you for your help.

Kenneth

 Nice, but I'm still finding the same bug when communicating between R and
 Tinn-R:
 
  source(.trPaths[5], echo=TRUE, max.deparse.length=150)
 
 So I still have to use the last version of Tinn-R which doesn't have that
 problem (Tinn-R 1.19.4.7).

  Dears users,
 
  A new version of Tinn-R was released today. Below details:
 
  2.3.7.0 (Nov/22/2010)
 
 * Bug(s) fixed:
   - A bug related with the intermittent loose of connection
  (or appear to freeze) with Rgui.exe was fixed.
 * The versions 2.3.6.4, 2.3.6.5, 2.3.6.6 and 2.3.6.7 restricted to
  pre-release testers.
 * The Application options interface was a bit changed:
   - The Application options/R/Rterm was split in two tabs:
  Error and Options. The tab Error has a new option: Try to find error
  in the editor. It enables the user to set Tinn-R in order to find
  errors in the editor when sending instructions to Rterm.
 * This version is full compatible with Windows 7 and R 2.12.0.
 * The component XPmenu was removed from the project. Windows XP
  users, perhaps, will find the Tinn-R appearance less attractive, but
  the applicative is now more stable. As soon as possible, the project
  will get a better option for skins.
 * Parts of the source code were optimized.
 
  All the best,
  --

Hi R users:

I will like to know if there is any set of packages that

Aquatic Ecosystem Dynamics Model) works.

It is an 3D hidrodynamic and ecology modelling simulation.

[R] Partialy SOLVED Re: Problems with pdf device using plot glht function on multcomp library.

[Kenneth Roy Cabrera Torres]

Hi R users:

I found a workaround for the problem I posted today.

I simple use Cairo library, then I use CairoPDF() function,
and it works!!!

The reason maybe is the acrobat reader, because the okular reader
from Ubuntu Linux shows the graphics just right.

Thank you for your help and advice.

Re: [R] WriteXLS problem

Maybe dataframes2xls package have the same problem.

But xlsx take too much time to write it down.

 The maximum number of rows in more editions of Excel.2003 was

 LIMITATIONS
 The following limits are imposed by Excel:
 
 Description Limit --- --
   Maximum number of chars in a string 32767
   Maximum number of columns 256
   Maximum number of rows 65536
   Maximum chars in a sheet name 31
   Maximum chars in a header/footer 254
 The minimum file size is 6K due to the OLE overhead. The maximum file  
 size is approximately 7MB (7087104 bytes) of BIFF data. This can be  
 extended by installing Takanori Kawai's OLE::Storage_Lite module 
 http://search.cpan.org/search?dist=OLE-Storage_Lite

[R] WriteXLS problem

[Kenneth Roy Cabrera Torres]

Hi R users:

I don't know if you have had the following problem trying to
export to an xls format file in a non windows platform.

I try to use the following packages:
1. dataframes2xls (version 0.4.4) (with phyton 2.7 and 3.1)
2. WriteXLS (version 1.9.0) (with perl and testPerl working)

Even xlsx package that take too long and do not finish.

The data frame I try to export has 269363 row and 116 columns.
In the first one (dataframe2xls) I get this message:

Traceback (most recent call last):

SyntaxError: invalid syntax

Using the second option I get this message:

Object '089' not found.

Im using this R platform:

Locale:

Is the only solution to export to .csv and then
to .xls format with other program like openoffice?

Thank you for your help and advice.

 Hi,
 
 Are you sure you used the correct syntax and object names? It might just 
 be because of that...(reading the error messages)
Im sure, because it works with write.csv or write.table.
 There is another function, xlsReadWrite::write.xls(), that I like a lot: 
 it is really easy to use and does not require Perl or Python.
Unfortunately it works on windows, and I am in a non windows platform
(ubuntu).

Thank you for you advice and help.

Re: [R] WriteXLS problem

[Kenneth Roy Cabrera Torres]

I use the following sintaxis for the packages:

For WriteXLS I use:

writeXLS(todo2009,todo2009.xls)

And for dataframes2xls I use:
dataframe2xls::write.xls(todo2009,todo2009.xls)

 Sure? You are making the incorrect assumption that those write  
 functions have the same syntax. At least for WriteXLS that assumption  
 is false. The help page clearly states that the objects need to be  
 quoted rather than being referred to by their naked names. The error  
 you are getting with your second option suggests to me that you  
 offered an unquoted name of an object.
 
 You can offer a vector of quoted names of dataframes to WriteXLS and  
 each named dataframe will be converted to a worksheet within the  
 workbook.

[R] Stack with factors

[Kenneth Roy Cabrera Torres]

Hi R users:

I found that I cannot stack() a data.frame with factors.

db1-data.frame(replicate(6,factor(sample(c(A,B),6,replace=TRUE
str(db1)
db2-stack(db1)
db2

db2 does not have any row.

How can I stack them by the variables X1,X2,...,X6?

Thank you for your help.

[R] Help with R in ubuntu (more organized 2)

[Kenneth Roy Cabrera Torres]

Dear R users:

Maybe it is a silly question, but I'm don't understand what am I doing
wrong.

In a new karmik koala ubuntu installation I compile the last patched 2.10.1
version of R.

Every thing was right (I install all the dev libraries I need).

First I type:

./configure  --enable-R-shlib

And I obtain:

R is now configured for i686-pc-linux-gnu  Source directory:  .
Installation directory:/usr/local
C compiler:gcc -std=gnu99  -g -O2
Fortran 77 compiler:   gfortran  -g -O2
C++ compiler:  g++  -g -O2
Fortran 90/95 compiler:gfortran -g -O2
Obj-C compiler: gcc -g -O2
Interfaces supported:  X11, tcltk
External libraries:readline, ICU
Additional capabilities:   PNG, JPEG, TIFF, NLS, cairo
Options enabled:   shared R library, shared BLAS, R profiling, Java
  Recommended packages:  yes


Then I type make, following with:
sudo make install.

Then when I try to call R it shows me this message:

Fatal error: unable to open the base package

But if I work as superuser, like sudo R, everything works fine.

I understand that it is a privileges issue, but where and how can I fix the
problem?

Thank you for your help.

Sorry for the newbee question.

Kenneth

[R] How to report or correct translations typos?

[Kenneth Roy Cabrera Torres]

Hi R users and developers:

Thanks to Mr Pablo Emilio Verde for his constribution
to the spanish translation for R messages he makes a very
good job.

I find a tiny typo on the translation,
in particular on the es.po file line 7312 it says:
pueto
it should be:
puerto

How can anybody might correct a typo or which is the
best way to correct it on a future patch?

Thank you for your help.

[R] lapply assign to list

Hi R users:

I got an error that l1 is not found.

This is a sample code:

f1-function(i,l1){

  l1[[i+1]]-i
  return(i)
}

z1-list(x=100,NULL,a=c(1,1))

My final goal is to update the value of
each list component to use it in the following
step.

I see that print function founds l1[[1]],
but the assign instruction not.

Thank you for your help.

 Make a function with an argument zn and

 You can leave out the local() then.
 E.g.,
  g - function(zn) {

 +value - lapply(1:3, f)
 +list(value=value, zn=zn)

  g(list(A, 11:13, 1+2i))
 $value
 $value[[1]]

 $value[[2]]
 [1] 1.414214
 
 $value[[3]]

Re: [R] OpenOffice Calc ODBC equivalent (SOLVED)

 As far as I know, nothing has changed vis-a-via ODBC connectivity TO  
 OpenOffice files. You can use ODBC FROM OpenOffice to connect to  
 external data sources.
Yes, I found that too.
 A search of CRAN does not reveal any packages/functions to would  
 appear to provide a facility to directly write data frames to a Calc  
 file. However, you can always write to a XLS file, 
Yes, I am going to do that.
 open it in Calc and  
 re-save it as a native Calc file. Of course, anyone with Calc can open  
 an XLS file, so you are not losing much in terms of portability by  
 saving to an XLS file and distributing that. You also make it easier  
 for folks who may be using other 'office' applications that do not  
 have import filters for OO.org file formats.

I was looking for xlsReadWrite package, but it seems that
it is removed form the CRAN repository, then I found your WriteXLS
package, which I am going to use.

I see that dataframes2xls is other package that can helps me too.

[R] OpenOffice Calc ODBC equivalent

[Kenneth Roy Cabrera Torres]

Hi R users:

I am using RODBC to create some new .xls files each with
several sheets (about 100) with sqlSave() from a data.frame
inside R  without any problem, but on windows XP platform.

I would like to know if it is posible to make a similar 
solution on linux with openoffice?

RODBC work only (for the moment) with .xls on windows,
via the ODBC driver.

Is it posible to make the same thing on openoffice?
I mean, an .odt file with several sheets each, generated from 
a data.frame in R?

I would like to just use

sapply(list1, somePlotfunction)

and plot for each graphic in the title have the name of the member of
the list.

Thanks to Dr. Ripley and Dr. Murdoch for the workaround

Now, with the perl=TRUE option added it works perfect (with the full

alumnos$AL_NUME_ID-gsub((^ +)|( +$),,alumnos$AL_NUME_ID,perl=TRUE)

I am going to test it with the patched version, that seems to work

[R] Stack overflow in R 2.10.0 with sub()

[Kenneth Roy Cabrera Torres]

Hi R developers:

Congratulations for the new R 2.10.0 version.

It is a huge effort! Thank you for your work and dedication.

I just want to ask how to make this strip blank function
to work again (it works on R.2.9.2).

alumnos$AL_NUME_ID-sub((^ +)|( +$),,alumnos$AL_NUME_ID),)

alumnos is a data base with 900.000 rows and 72 columns.
and alumnos$AL_NUME_ID is a character variable read form
a mysql database.

The system shows me this message:

Error: C produce desborde de pila en 'segfault'

It seems a stack overflow problem, but it works on R 2.9.2!

Thank you for your help, and again, thank you for your work!!!

Re: [R] Stack overflow in R 2.10.0 with sub()

Dr. Murdoch:

I am puzzled!
As you adviced me I do this:

x - as.character(alumnos$AL_NUME_ID)
x - x[-seq_len(length(x)/2)]
y - gsub((^ +)|( +$),,x)

And it fails,

But, trying to locate the problem I do:

x - as.character(alumnos$AL_NUME_ID)
x - x[-seq_len(length(x)/2)]
x - x[seq_len(length(x)/2)]
y - gsub((^ +)|( +$),,x)

works

x - as.character(alumnos$AL_NUME_ID)
x - x[-seq_len(length(x)/2)]
x - x[-seq_len(length(x)/2)]
y - gsub((^ +)|( +$),,x)

works

Now, both works!!!

So, I am puzzle!!! I cannot locate the problem.
Thank you for your advice.

And it fails again without showing me the invalid string errors.

I then make this:

and it works, then I type

 y - gsub((^ +)|( +$),,x[1:20]) #(x length is 454035)

and it works...

But I start to make a manual binary search,
I found something that stills puzzle me.

y - gsub((^ +)|( +$),,x[1:261570])

works, but sometimes fails (after I restart R),
it always fails with index greather than 262000.

I see that there are not something inusual arround 261570.

[R] gnu ODBC driver for ORACLE in WinXP platform?

[Kenneth Roy Cabrera Torres]

Hi R users and Dr. Uwe Ligges:

I read on the ROracle pre-compiled binary README file that:

Although the package ROracle passes make check, it seems to be
dangerous to distribute it:
I do not have the software available this package depends on.

Why it is dangerous to use ROracle for windows?
What software does ROracle depends on in windows platform?

Is there a GNU solution for an ODBC driver on windows XP platform
for ORACLE for use it with RODBC?

Thank you for your help.

[R] math symbol + value of a variable in legend.

[Kenneth Roy Cabrera Torres]

Hi R users:

I will like to have a legend with math symbols and also with
the value of a variable.

But I cannot obtain both at the same time (symbol + value of a
variable):

Here is a reproducible example:

m1-5
m2-12
plot(1:5,1:5,type=n)
legend(topleft,legend=c(paste(expression(mu),=,m1),expression(paste(mu,=,m2))),lty=1:2)

Thank you for your help.

 legend(topleft,
 legend=c( eval(substitute( expression(mu[i] == m1),  
 list(i=1, m1=m1) )) ,

Re: [R] How to google for R stuff?

---BeginMessage---
I use to install the R Site Search Sidebar in firefox.

Unfortunalely you can not install it in new versions
of firefox unlees you disable checkCompatiblity and
checkUpdateSecurity on firefox (which is not recommendable).
Still I do it and is my favorite search engine when 
I am trying to find any topic in some R package.

I love the R logo in the bottom left side of the firefox browser.
Somebody told me that it is like the secret logo the hackers
use on the film The Net (1995) with Sandra Bullock.

Have a good R searching.

 Hi!  I'm new to R programming, though I've been programming in other
 languages for years.
 
 One thing I find most frustrating about R is how difficult it is to use
 Google (or any other search tool) to look for answers to my R-related
 questions.  With languages with even slightly more distinctive names like
 Perl, Java, Python, Matlab, OCaml, etc., usually including the name of the
 language in the query is enough to ensure that the top hits are relevant.
  But this trick does not work for R, because the letter R appears by itself
 in so many pages, that the chaff overwhelms the wheat, so to speak.
 
 So I'm curious to learn what strategies R users have found to get around
 this annoyance.

[R] Extracting correlation in a nlme model

[Kenneth Roy Cabrera Torres]

Hi R users:

Is there a function to obtain the correlation within groups
from this very simple lme model?

 modeloMx1
Linear mixed-effects model fit by REML
  Data: barrag 
  Log-restricted-likelihood: -70.92739
  Fixed: fza_tension ~ 1 
(Intercept) 
   90.86667 

Random effects:
 Formula: ~1 | molde
(Intercept) Residual
StdDev:2.610052 2.412176

Number of Observations: 30
Number of Groups: 3 

I want to obtain \rho = \sigma_b^2 / (\sigma_b^2 + \sigma^2)

I know that I obtain \sigma_b^2 and \sigma^2 with

 VarCorr(modeloMx1)

molde = pdLogChol(1) 
Variance StdDev  
(Intercept) 6.812374 2.610052
Residual5.818593 2.412176

But, I want to know if I can obtain
\rho = 6.8123/(6.8123 + 5.8185) = 0.53934 straightforward.

Thank you for you help.

I discovery this behavior when I try to use old scripts that uses
the aggregate() function, but now it fails on my old scripts.

[R] aggregate() problem on last patched version

[Kenneth Roy Cabrera Torres]

Hi R users and developers:

Several hours ago I post a problem with the aggregate() function
using the last patch version of R.
(R version 2.8.1 Patched (2009-03-18 r48193))

I do compile again the 2.8.1 plain version (not patched) and
now it works again, both the examples and  my old scripts that
use this function.

What are the changes on the patched version that produces this
behavior on this particular function?

Thank you for your attention.

[R] [Fwd: Re: Graphic with several curves]

 Asunto: Re: [R] Graphic with several curves
 Fecha: Mon, 23 Mar 2009 17:02:48 -0500
 
 try matplot(),
 
 but you have to transpose the matrix
 
 with option type=l.
 
 Example:
 
 data1-data.frame(X1990=c(5,15,3,20,10),X1991=c(20,1,14,8,3),X1992=c(6,11,22,55,14))
 data2-t(data1)
 matplot(as.integer(substring(row.names(data2),2)),data2,type=l)
 
 Data frames names cannot start with a number. R change it to an X,
 then when you transpose I obtain the substring with the number that I
 need.
 
 Hope, this helps (HTH)

   Problems:
   1. I expect that the boxplot for the B and Y combination
 would be the most thick, and in second place the A and X
 and the last the X and B combination.
 
 I think you want something like
 
 bwplot(categ2 ~ cont1 | categ1, data=data1,
panel = function(..., box.width) {
panel.bwplot(...,
 box.width = as.numeric(cont2[packet.number(), ]))
})
 
   2. Why the other lines in the box of the boxplot?
 
 You are providing 6 width values for 3 boxes in each panel; the values
 are being recycled and each box is being drawn twice, with different
 widths.

[R] 2^k designs anova

[Kenneth Roy Cabrera Torres]

Hi R users:

How can I obtain the same anova table 
for the effects for a 2^k experiment design that MINITAB shows
(and authors recommends Box, Hunter,  Hunter).

http://www.stat.psu.edu/online/development/stat503/06_2k/04_2k_unreplicate.html

Here is the code that I use for this case:

D-C-B-A-c(-,+)
design-expand.grid(A=A,B=B,C=C,D=D)
design$yield-c(45,71,48,65,68,60,80,65,43,100,45,104,75,86,70,96)
model1-aov(yield~A+C+D+A:C+A:D,data=design)
summary(model1)
model.tables(model1,se=T)

Thank you for your help.

Kenneth

[R] An example of the boxplot thickness problem

[Kenneth Roy Cabrera Torres]

Hi R users:

I reproduce the problem that I have with the
boxplot thickness:
--
# A data frame:
set.seed(123)
cont1-c(rnorm(10,1),rnorm(5,3),rnorm(12,5),rnorm(14,3),rnorm(4,5))
categ1-factor(c(rep(A,10+5+12),rep(B,14+4)))
categ2-c(rep(Z,10),rep(Y,5),rep(X,12),rep(Y,14),rep(X,4))

data1-data.frame(cont1,categ1,categ2)

# This is the variable that I want that each boxplot
# be thickness proportional. (could be any other, the only
# condition is that I have a number (or NA) for each combination of the
# two categorical variables).
cont2-tapply(cont1,list(categ1,categ2),length)/length(cont1)

require(lattice)
# This is the standard boxplot
bwplot(categ2~cont1|categ1,data=data1)
# I try:
bwplot(categ2~cont1|categ1,box.ratio=cont2,data=data1)
# This one also
bwplot(categ2~cont1|categ1,box.ratio=t(cont2),data=data1)


Problems: 
1. I expect that the boxplot for the B and Y combination
   would be the most thick, and in second place the A and X
   and the last the X and B combination.

2. Why the other lines in the box of the boxplot?

Thank you for your help.

[R] thickness of boxplots

[Kenneth Roy Cabrera Torres]

Hi R users:

How can I obtain with bwplot boxplots with bwplot whose box width
will vary acording to other variable.

bwplot(categ1~continuos|categ2,box.ratio=continuos2,data=data.base)

But it doesn't work as I expected.

Thank you for your help.

[R] [Fwd: Re: Cómo convertir un objeto da ta frame en una tabla csv]

[Kenneth Roy Cabrera Torres]

---BeginMessage---
Hi Ricardo:

I don't understand your question, not because it is in spanish,
but because I will like to know what are you pretending to do.

data.frame is an R object.
csv is a external ascii format for database tables.
geodata is an internal geoR object (a list).

The usual steps are:

.csv external file -  data.frame R object (with read.csv or read.csv2)
data.frame R object - geodata (with as.geodata() geoR function)

If you want to write to an external file a geodata object, and
later read it back to R you should use save() to write and
then load() to recover it. (?save and ?load)

Hope that will help you.

Kenneth

Re: [R] encoding accentsand tildes in R Macosx

[Kenneth Roy Cabrera Torres]

Hi Carlos:

I think you got a encoding problem.
Maybe is esier to convert it.

I don't know how to convert in Mac OS, but
in linux you can use iconv that converts many codes
to other.

Is the original file form a windos$ OS system?
Maybe the encoding is in windows-1256 and you need
to convert to a compatible MAC enconding.

Hope this helps.

 Hello,
 In R under  Mac OS X 10.5.4 I've had problems when I've tried to read a 
 data.frame with characters including tildes and accents.
 For instance Florea is changed to Flore\x96a and Ranchera is changed to 
 Rancher\x92a 
 In the code:  
 section-read.table('Sectiondic.txt',sep='\t',header=T,stringsAsFactors=F,encoding=

 I've changed the  encoding argument but I have not could find the solution.
 Any suggestion?
 
 Thanks a lot

[R] Insurance review statistical methods

[Kenneth Roy Cabrera Torres]

Hi R users:

I will like to know if somebody works on insurance statistics
(actuarial problems) and had use TRICAST, and can tell me
if with all the R tools it can be build a solution
like TRICAST or similar.

In a word:
Do you think that  R has all the statistical tools
(I mean modeling tools) to make a job similar to TRICAST?

Does TRICAST has modeling tools that are not implemented
on R yet?

Thank you for your help.

Kenneth

Hi R Guru:

Thank you for your answer!

No, Dr. Velez, it is a closed source and propietary software,
that several companies here in Medellin are starting to use
to face actuarial problems.
