similar to: serialized plot object (2 years later)

Dear list, Using serialize it is possible to save the binary string representing an R object to a raw R vector. ## adapted from ?serialize x <- serialize(list(1,2,3), NULL) x I am looking for a way to capture the binary string that in normal use of graphics devices will be written to (most commonly) a file connection. jpeg(file = "test.jpg") plot(1:10) dev.off() In other

L.S. Since some time there is a new r-project.org site as announced here: https://stat.ethz.ch/pipermail/r-announce/2015/000581.html The logo has changed on the site, but I fail to find a vector graphics file. For the previous logo I used to go to https://svn.r-project.org/R-dev-web/trunk/Logo/ Is there anything similar for the new logo? Many thanks in advance. Kind regards, Tobias --

Many thanks, Duncan. We will check the prerelease versions of R 3.2.1.

L.S. In this bug report https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14493#c1 it is mentioned that after moving an R installation one should regenerate the Rscript executable. Is there an easy way to do so (after an R installation has been moved)? I have not found any information in the R installation and administration manual. Many thanks in advance for any pointer. Best wishes,

Dear list, Is there an exact formula / safe rule of thumb that allows one to express the value of --max-ppsize as a function of the value of getOption("expressions") ? ?options tells "If you increase it [the expressions option], you may also want to start R with a larger protection stack". Motivation is to determine stack size of a Java vm used to launch R with a given

Dear list, I'm trying to embed OpenBUGS in an R package for use of it on 64-bit Linux. In order to get the CLI working one has to compile C code contained in $OpenBUGS/Manuals/CBugs.html (copied to say CBugs.c) using gcc -m32 -o bugs CBugs.c -ldl I put the OpenBUGS distribution in the ./inst subdirectory of the package root. Where should I now put the CBugs.c and how

Dear list, Could someone enlighten me a bit on the exact format used for text help pages as I see them on Windows in the help/ folders of (compiled) package roots. When opening an example of these files in a text editor (?Bessel in GNU emacs), the file is displayed as follows: _^HB_^He_^Hs_^Hs_^He_^Hl_^H _^HF_^Hu_^Hn_^Hc_^Ht_^Hi_^Ho_^Hn_^Hs Bessel package:base

Hi all, Sorry if this doesn't end up in the thread. Tobias Verbeke forwarded that e-mail to me, because he thought I would be interested in maintaining the Programming Tools CTV. I wasn't subscribed to R-devel yet, but I would indeed like to volunteer to maintain the Programming Tools CTV. It will be my first time creating a CTV, so some guidance on getting it setup will be appreciated.

This is a best practices / style question. The way I use RODBC is I something like this: > foo <- sqlQuery(db, "select * from foo") > apply(foo, 1, function{...}) That is, I use apply to iterate over each result -- row -- in the RODBC-produced dataframe. Is this how one generally wants to do this? My concern is that when apply iterates over the rows, it uses as.matrix()

I'd like to have something like seq() where I can pass in a length of the desired sequence and a right limit so that the sequence goes up to the limit and then starts again from 1. # works now seq(from=2, length.out=3) [1] 2 3 4 # what I want seq(from=2, length.out=3, rlimit=3) [1] 2 3 1 # additional examples of what I want seq(from=2, length.out=4, rlimit=3) [1] 2 3 1 2 seq(from=2,

Dear list, I would like to study the dynamics of functions using R (instead of mathematica e.g.), i.e. the behavior of points under iteration of a function. So I tried (in vain) writing a function myfunction <- function(f,n,x){...} in order to compute f^{n}(x), f^{n}(x) being the function f composed with itself n-1 times. n is a natural number, and the argument x is the abscissa of the point I

In R 2.9.2, > URLdecode(c("a%20b", "b%20c")) [1] "a b" Warning message: In charToRaw(URL) : argument should be a character vector of length 1 all but the first element will be ignored Could URLdecode be modified to actually process all elements of the vector, not just the first? Thanks in advance

I know that if I have a function that returns multiple values, I should do return(list(foo, bar)). But what do I do on the recieving end? fn <- function(x) { return(list(foo, bar)) } I know that at this point I could say values.list <- fn(x) and then access values.list[1] values.list[2] But that's hideous. I'd rather be able to say something like list(local_foo, local_bar)

I have a named vector: > z <- c(1, 2, 3, 2) > names(z) <- c("a","b","c","b") > f <- c("b","c") I want to know the index in z of the first occurrence of each of the values in f. One implementation is > sapply(f, function(x) which(names(z)==x)[1]) b c 2 3 Is which() smart enough to stop when it finds in z the

> a <- sqlQuery(irrdb, "select count(field) from mytable where field = 1") > print(a) count(field) 1 8 > paste(a) [1] "as.integer(8)" Why the as.integer() representation? I later pass the result into this write.html.table(), and what I get is rows of as.integer()... when all I want is the integer itself. as.integer(31) as.integer(21)

Dear Willem, Personally, I use the R-forge project for the distribution CTV : https://r-forge.r-project.org/projects/ctv/ It?s an alternative option to github.

Hallo, does a package for Matlab exist in R? If yes, where can I find it and how can I install it under R? Thanks, Corinna

The following three calls all produce the same result (my machine is in EST): > as.POSIXct(0, tz="", origin=ISOdatetime(1970,1,1,10,0,0)) [1] "1970-01-01 10:00:00 EST" > as.POSIXct(0, tz="EST", origin=ISOdatetime(1970,1,1,10,0,0)) [1] "1970-01-01 10:00:00 EST" > as.POSIXct(0, tz="GMT", origin=ISOdatetime(1970,1,1,10,0,0)) [1]
