Re: [R] [FORGED] Re: How create columns for squared values from previous columns?

[Mike C]

Thanks Rolf.
I was just a bit frustrated that R wouldn't generate dummy variable names on 
the fly.

Also, another question, if I want to put column 5 at column 3,

dat[, 3:5] <- dat[, c(5,3,4)]

It does not work, why?

Well, if the names bizzo is your only worry, you could hit the result
with data.frame() *after* cbinding on the squared terms:

dat <- matrix(rnorm(30),ncol=5)
dat <- cbind(dat,dat[,1:3]^2)
dat <- data.frame(dat)
names(dat)

And as you indicate, the names of a data frame are easily adjusted.

I wouldn't lose sleep over it.

cheers,

Rolf Turner

P.S. You could also do

 names(dat) <- make.unique(names(dat))

to your original idea, to get rid of the lack of uniqueness.  The result
is probably "undesirable" but.

OK， thanks for the info
 I apologize. I must have misread or misremembered.

I have found the answer btw. R
Cache serves the said purpose perfectly.

   X1  X2  X3 X4  X5

Suppose I want to add columns X6, X7, X8, where
X6 = X1^2
X7 = X2^2

I am thinking of using apply(), but df asks for column names, what's a
quick way to generate names on the fly?

Thank you very much!

Re: [R] Opencpu and caching

[Jeff Newmiller]

You have already been told this is the wrong list for these questions. Go ask 
in the OpenCPU support areas.

My very limited understanding of OpenCPU is that what you are asking for is 
specifically not supported. You need to setup your own function that does 
everything before it returns.

[R] Opencpu and caching

[Jake Stone]

I am new to opencpu. My specialty is java. I use R for very specific
analyses.

*PROBLEM*
My understanding is that each API call to opencpu opens a new R session.
My function will classify the data input using the predict method of a
linear discriminant analysis (lda from MASS package).
The initial linear discriminant analysis on 10+ cases and 150+ factor
levels takes time (over 30 seconds). This function returns a list.
The subsequent prediction function is quick and returns a simple vector.


*APPROACH*
I run one opencpu function to run the initial lda. This only needs to run
once.
I want my second function to ONLY run the predict function. This is
possible if the lda is held as a global variable.
My understanding is that global variables are not possible in opencpu. So I
will have to cache the lda on the file system.
In sum, I need to run the lda just once and hold the analysis (a list)
either in memory or on the file system. I then retrieve the lda analysis
when predict is called.

*QUESTION*
Which approach is best, and how to implement?
1. I could use an opencpu function that creates and returns the lda. Then
when I call a prediction, I could retrieve the lda object (a list) from the
file system. But how do I retrieve the list from the file system. How
does opencpu even know where it is?
2. I could use r.cache package. I haven't used this package before but the
docs suggest it is a solution. Will this work?

Any advice would be deeply appreciated.

jake

Re: [R] Data.table vs dplr handling multiple variables

[Jeff Newmiller]

All approaches have strong points and weak points. Your question has no clear 
answer.

I happen to like dplyr for many things (including lots of timestamp values), 
but base R is always there to solve problems if the analysis framework-du-jour 
has troubles. So learn base R ways of doing things if nothing else. 

For next time: please read the Posting Guide. Give us a minimal example in R of 
what you are trying to accomplish along with your description and what you 
think the right answer will look like (consider using the reprex R package), 
and turn off HTML in your email program at least for your mails sent to this 
list because HTML gets damaged to varying degrees by the mailing list and then 
we are left puzzled about what you were asking.

Hi,

In package ‘VecStatGraphs3D’ is a DrawDensity3D-function in which the
rgl-device size is defined as
r3dDefaults$windowRect=c(0,0, WSizeWidth, WSizeHeight).

To save, for instance, a png-snapshot, we can use rgl.snapshot()-function.

The size of the file is dependent on the window and thus your screen and
video card.

Can we somehow produce  larger images virtually, for example, 4k-images
(3840x2160)?



I don't know of a way to do that.  If you can create a virtual screen of 
that size, and your system allows you to create a window on it, then it 
might work:  but I haven't come across a way to do that that also 
supports OpenGL in the virtual window.

   "Ccoxfit6" not available for .Call() for package "survival"


As far as I can see, that line doesn't appear in the current survival
source code, it's from some earlier version of the package.  The current
one has

coxfit <- .Call(Ccoxfit6,
  as.integer(maxiter),
  stime,
  sstat,
  x[sorted,],
  as.double(offset[sorted]),

  as.double(control$eps),
  as.double(control$toler.chol),
  as.vector(init),
  as.integer(1))  # internally rescale

There are several differences, the one leading to the error being the
change from "Ccoxfit6" in quotes, to Ccoxfit6 not in quotes.  That
corresponds to the difference between a registered symbol and an
unregistered one.


I think it's worthwhile to point out that non-exported symbols are
available using ':::'.  See WRE Section 5.4.

So, after fixing the argument list, just use '.Call(survival:::Ccoxfit6,
)' instead of '.Call("Ccoxfit6", , PACKAGE = "survival")'.



Yes, and in another section it says "Using foo:::f instead of foo::f 
allows access to unexported objects. This is generally not recommended, 
as the semantics of unexported objects may be changed by the package 
author in routine maintenance."

Henric Winell





Without seeing the code that led to the error message I can't really say
how the error came about.  There are a few ways:

- The user has a copy of the coxph.fit function from an older version of
survival saved in their workspace, and are using that one instead of the
current one.

- Some part of your code returns functions, and one of those is making
this call based on an object produced in an earlier version of survival.

- There are really two versions of survival on the

[R] Data.table vs dplr handling multiple variables

[Ek Esawi]

Hi All—

I am often working with large datasets with multiple variables (integer,
decimal, string, complex, date, and time) that require processing,
cleaning, etc. I am relatively new to R and I would like to get some input
on the following issue: I am trying to figure out which R-package(s) is
most suitable for my work. I looked into data.table and dplyr. Both are
very good but I found out that data.table does not handle time data well
(one has to use fast time package) and not sure whether dplyr does the same
or not. I am not sure about their handling of other variables listed above.
I like data.table.


The questions: (1) which package should I invest on learning and how to
deal with issue like time data and possibly other variables such complex
numbers, date, etc.? (2) What is the “best” practical solution for such
issue?



Thanks in advance,


EKE

Re: [R] Error with installed.packages with R 3.4.0 on Windows

Dear Peter,

It actually breaks install.packages(). So it is not that innocent.


I don't think he meant that it is harmless, he meant that the fix is 
easy, and is in place in R-patched and R-devel.  You should use 
R-patched and you won't have the problem.


More generally, there's a lot more variety of systems in the wild than 
on our test machines, so we really do rely on people testing things in 
the alpha/beta/rc phase.  In this case we saw the error too late to fix 
it (as I recall, it was very late in rc).  If more people had tested, we 
might have found it earlier.

Yes, we noticed this in the last days of the code freeze before release and
shied away from inserting a workaround, partly because we couldn't see what
the root of the problem might be.

For the purposes of installed.packages it is relatively harmless to treat
the NA condition as FALSE, since it is just a matter of whether a cache is
valid. I.e., it might cause an unnecessary cache rebuild. For other
situations it might be more of an issue.

The workaround (NA -> FALSE, basically) is in place in R-patched and
R-devel.

I am working with R 3.4.0 on Windows. I didn't get this error with R

3.3.3.

Apparently, file.mtime() is returning NA well applied to a directory, and
this causes the entire && expression to be NA, then the "if" fails because
it needs either T or F.
The source of "installed.packages" seems to be roughly the same as in R
3.3.3, so I wonder if there have been other changes in R, maybe the

logical

operators, that would make this function fail.

Any idea?

[R] Larger rgl-images?

[Atte Tenkanen]

Hi,

In package ‘VecStatGraphs3D’ is a DrawDensity3D-function in which the 
rgl-device size is defined as

r3dDefaults$windowRect=c(0,0, WSizeWidth, WSizeHeight).

To save, for instance, a png-snapshot, we can use rgl.snapshot()-function.

The size of the file is dependent on the window and thus your screen and 
video card.


Can we somehow produce  larger images virtually, for example, 4k-images 
(3840x2160)?

[R-es] ggplot dentro de una función

[Rubén Coca]

Hola a todos,
Partiendo de:

library(ggplot2); library(data.table)

datos <- data.table(Date = seq.Date(as.Date("2017-01-01"),
 as.Date("2017-01-10"),
 by = "day"),
 V1 = rnorm(10),
 V2 = rnorm(10))

Quiero crear una función para pintar un gráfico cuyos argumentos sean el
data table y la variable a pintar en el eje de las x. Se me ocurre ésta:

grafico <- function(dt, varx) {
  ggplot(dt, aes(x = Date, y = varx)) +
geom_point()
  ## un montón de código de configuración del gráfico, etc
}

grafico(datos, V1)

Pero ggplot dice que no encuentra V1...
Error in eval(expr, envir, enclos) : object 'V1' not found
In addition: Warning message:
In eval(expr, envir, enclos) : restarting interrupted promise evaluation

Alguna sugerencia o nuevo enfoque?
Muchas gracias

Rubén

This has been discussed in R-help by multiple people.  You have a

resolving .C calls has

changed.   The sessionInfo command should report survival version 2.41-3.

As far as I can see, that line doesn't appear in the current survival 
source code, it's from some earlier version of the package.  The current 
one has


coxfit <- .Call(Ccoxfit6,
  as.integer(maxiter),
  stime,
  sstat,
  x[sorted,],
  as.double(offset[sorted]),
  weights,
  newstrat,
  as.integer(method=="efron"),
  as.double(control$eps),
  as.double(control$toler.chol),
  as.vector(init),
  as.integer(1))  # internally rescale

There are several differences, the one leading to the error being the 
change from "Ccoxfit6" in quotes, to Ccoxfit6 not in quotes.  That 
corresponds to the difference between a registered symbol and an 
unregistered one.


I think it's worthwhile to point out that non-exported symbols are 
available using ':::'.  See WRE Section 5.4.


So, after fixing the argument list, just use '.Call(survival:::Ccoxfit6, 
)' instead of '.Call("Ccoxfit6", , PACKAGE = "survival")'.



Henric Winell





Without seeing the code that led to the error message I can't really say 
how the error came about.  There are a few ways:


- The user has a copy of the coxph.fit function from an older version of 
survival saved in their workspace, and are using that one instead of the 
current one.


- Some part of your code returns functions, and one of those is making 
this call based on an object produced in an earlier version of survival.


- There are really two versions of survival on the search path (or 
perhaps copied bits of one), and this call isn't in survival 2.41-3 at all.

[R] Overriding lack of i386 build for ROracle when updating packages

[Laviolette, Michael]

Since I query my Oracle warehouse often, I load the ROracle package on startup. 
Whenever I update packages from RStudio (which actually runs the 
install.packages function) with ROracle loaded, I get the following error:

Error: package 'ROracle' is not installed for 'arch = i386'

Unloading the package doesn't help; I have to edit my startup script to not 
load ROracle, then restart R, update packages, and restore my original startup 
script. I don' t have any use for 32-bit ROracle and am not sure that it exists 
(the package archive doesn't contain a "libs/i386" folder. Does anyone know of 
a way to override the lack of an i386 build when installing other packages?

Thanks,
M.L.

Re: [R] Error with installed.packages with R 3.4.0 on Windows

[Dimitri Liakhovitski]

When I click on "r patched snapshot build" here
, it take me here
 , it says: Download
R-3.3.3 Patched build for Windows

However, I am unclear how can one get to the patched 3.4.0 version?
Thank you!

Typo: last line should be

Even better, use

Re: [R] Different output for "if else" and "ifelse" that I don't understand

[William Dunlap via R-help]

ifelse's vectorization messes this up.

You could replace your original
  if (class(try(list(...), silent=TRUE))=="try-error") p3p <- list() else
p3p <- list(...)
with
  p3p <- if (class(try(list(...), silent=TRUE))=="try-error") list() else
list(...)
instead of using ifelse, since the return value of 'if ... else ...' is the
value of whichever branch was taken.

Even better, use
  p3p <- try(list(...), error=function(e) list())

Re: [R-es] Ingresar datos dentro de R sin Excel

[Javier Marcuzzi]

Estimado Wilmer

Es posible, le indicaron algunas opciones, pero no es recomendable, si no le 
molesta use el programa que más de gusta, guarde en csv, luego los importa con 
solo una línea de código, salvo para algunas pruebas específicas yo opto por 
tener los datos separados de R, aunque si sin pocos es posible escribirlos en 
R, pero casi como excepción.

Hola, buenos días.

Quisiera saber si existe alguna función o libreria en R que simule la
ventana de Excel para ingresar datos. No estoy hablando de importar datos
de excel a R, No.
Quisiera que dentro de R existiera el entorno para ingresar los datos
rapidamente y no pasar por la molestia de ingresar los datos a Excel y
luego tener que importarlos a R.

Muchas gracias.

Re: [R] Reading XML attriutes in R

[Ben Tupper]

Hi again,

It would be super easy if xml2::xml_attrs() accepted a list of attribute names 
and defaults values like xml2::xml_attr() does, but it doesn't.  Once you have 
a list of character vectors like that returned by your ...

ppt <- x %>% xml_find_all("precipitation") %>% xml_attrs()

..then you need only try to extract the fields you want.  Perhaps something 
like the following untested steps...

precip <-  tibble::as_tibble(do.call(rbind, lapply(ppt, '[', c('unit', 'value', 
'type')) ))

colnames(precip) <- c('unit', 'value', 'type')

Bon chance!
Ben

P.S.  Don't forget to change your email client to send plain text messages to 
this list.  Typically rich text and html emails get turned into hash by the 
R-help list services.

Dear all,

stationarity which is in line with the corresponding graph, the ur.df()

Why does this happen?


This is likely due to different setting for the deterministic part of the 
model and/or the number of lags tested. The defaults of ur.df() are often 
not suitable for many practical applications which might to spurious 
significant results.


Could anybody explain the adf.test() function in more detail? How does 
adf.test() select the number of lags is it AIC or BIC and how does it 
take an intercept and/or a trend into account?


There is a deterministic trend and the default number of lags is selected 
by a heuristic.

For the purposes of installed.packages it is relatively harmless to treat
the NA condition as FALSE, since it is just a matter of whether a cache is
valid. I.e., it might cause an unnecessary cache rebuild. For other
situations it might be more of an issue.

The workaround (NA -> FALSE, basically) is in place in R-patched and
R-devel.

I am working with R 3.4.0 on Windows. I didn't get this error with R

3.3.3.

Apparently, file.mtime() is returning NA well applied to a directory, and
this causes the entire && expression to be NA, then the "if" fails because
it needs either T or F.
The source of "installed.packages" seems to be roughly the same as in R
3.3.3, so I wonder if there have been other changes in R, maybe the

logical

operators, that would make this function fail.

Any idea?

Re: [R] gap.barplot with means and standard error bars

Hi Bianca,
Try this:

gap.barplot(c(mean(SA),mean(AA),mean(CA)),
 gap=c(1,250),xlim=c(0.5,3.5),xaxlab=c("SA","AA","CA"),
 ytics=c(0,255,260,265),yaxlab=c(0,255,260,265))
barlabels(1:3,c(5,5,5),

 round(c(sd(SA),sd(AA),sd(CA)),3)))

It's a bit rough, but I don't have time for refinement tonight.

[R] Different output for "if else" and "ifelse" that I don't understand

[Marc Girondot via R-help]

Dear list-members,

During the test phase of a function, I run it interactively (in Rstudio) 
and the ... produces an error. Then I use this to read it:


if (class(try(list(...), silent=TRUE))=="try-error") p3p <- list() else 
p3p <- list(...)


It works fine; interactively I will get

> if (class(try(list(...), silent=TRUE))=="try-error") p3p <- list() 
else p3p <- list(...)

> p3p
list()

and within a function I will get a list with the ... value. Perfect.

I wanted to simplify the line by doing:

p3p <- ifelse(class(try(list(...), silent=TRUE))=="try-error", list(), 
list(...))


In interactive mode, it works but within a function, I don't get the 
names of the parameters. I don't understand the logic behind this 
difference. Have you an idea ?


Thanks

Marc

+   if (class(try(list(...), silent=TRUE))=="try-error") p3p <- list()

Re: [R] Reading XML attriutes in R

Thanks Ben, got it working, just want one more help on this,

If i have a node like:  and in some other city it
came like:  

How can i make my code to handle this dynamically? I am sorry to ask such
novice questions but it would be extremely helpful if you could help me
with this.

So, i would want my resulting data set from this code:- ppt <- (x %>%
xml_find_all("precipitation") %>% xml_attrs())
 if mode is no, then the three columns should come and values should be NA
and if values are populated then as is.

Unit Value  Type
NANA NA
3h0.0925 rain

Thanks again and in advance !
