I have a debugging environment for the survival package, perhaps unique to me, but I find it works very well. To wit, a separate directory with copies of the source code but none of the package accuements of DESCRIPTION, NAMESPACE, etc. This separate space does NOT contain a copy of src/init.c Within this I use R --vanilla, attach my .RData file, survival.so file, and away we go. That is,

I'm observing the following on different platforms: > parse(text='"\\x7F"') expression("\177") > parse(text='"\\x80"') Error: invalid multibyte string ... > parse(text='"\\xFF"') Error: invalid multibyte string However, cat("\x7F\n\x80\n...\xFF\n") works. Using R --vanilla. SYSTEMS GIVING THE ERROR: >

Hi, We recently switched from R2.7.0 to R2.8.1 but having problems tracking down this 'invalid multibyte character' encoding issue. Can someone point us how to solve this? > sessionInfo() R version 2.8.1 (2008-12-22) x86_64-unknown-linux-gnu locale:

A colleague?s R program behaved differently when I ran it, and we thought we traced it probably to different results from string comparisons as below, with different R versions. However the platforms also differed. A friend ran it on a few machines and found that the comparison behavior didn?t correlate with R version, but rather with platform. I wonder if you?ve seen this. If it?s not some

I have run into a problem when do loops with lots of elements in CentOS (I am a new user after using Ubuntu for many years). I am attaching two scripts, one called Looping_Centos_minimal_bug_OK.R which runs fine. I simply repeat a function call in it 15 times. However, if I repeat that function call 16 times, as in this one, Looping_Centos_minimal_bug_breaks.R I get the error, Error: unexpected

I have just upgraded to R 2.13 and have library(ggplot2) in my .Rprofile (among other things). when i start R I get an error message. Has something in the start up scripts changed? Is there a better way to specify the library calls in .Rprofile? Thanks for all of the help in advance.

Hi, When playing interactively with the S4 system, I've tried to define the following class: > setClass("A", representation("integer")) [1] "A" > showClass("A") Slots: Name: .Data Class: integer Extends: Class "integer", from data part Class "vector", by

Hi, I installed package 'lars' earlier tonight and did not get any sort of error message. ### ** building package indices ... ** testing if installed package can be loaded Loaded lars 0.9-8 * DONE (lars) ### However, when I try to load it, I get ### > library(lars, lib.loc = "~/R/x86_64-redhat-linux-gnu-library/2.11") Error : .onLoad failed in loadNamespace() for

I am getting failure of build and check, for an Rd file that has a long argument list. Guess diagnosis: a quoted string beyond a certain point in the argument list is fatal. Example: Use the function below, create an Rd file for it with prompt(). Move the .Rd file to the man directory (no need to edit it) and try building dart.control <- function(server=c("production",

Dear all, It seems that textConnection() can trigger a segmentation fault. The following script (using two large loops) makes this bug reproducible: for (i in 1:10000) { z=textConnection(NULL,open='w') for (j in 1:100) { write(runif(1)*1e6,file=z) write('\n',file=z) } close(z) } The bug could be reproduced on R-2.6.1, R-2.7.0 and on the latest R-devel

Dear Luke and others, I have many R versions on my machine and want to start a particular one when snow builds its cluster. (The same version I start snow from.) It seems that everything is set up correctly in defaultClusterOptions: > mget(ls(defaultClusterOptions), defaultClusterOptions) $homogeneous [1] TRUE $manual [1] FALSE $master nodename "maya.unil.ch" $outfile [1]

Is my understanding correct that the body() function currently can't return a function's body intact, in order, and as characters ready for editing? My testing and reading of body()'s help indicate that it can not. Here's what I'm seeing. Consider pasting 1+ and a function containing x^2 together to get 1+x^2 As you can see below, body() reports three

Hi, I get the following error when trying to remove a union class: > setClassUnion('a', c('matrix', 'numeric')) > removeClass('a') > sessionInfo() R version 2.15.3 (2013-03-01) Platform: i686-pc-linux-gnu (32-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8

I have very little knowledge about file encodings and would like to learn more. I've read the following pages to learn more:

Hi, Browser doesn't work properly with the compiler enabled.

Dear all I'd like to make a beeping sound in R, but alarm() doesn't beep? I checked ?alarm but I couldn't find any pointers to system configuration. Any ideas?

Hi, How can I make the cor(x, y, method="spearman") call to produce an error when the input to it (x, y) produces an error? Here is a simple example: > a <- c(0, 1, 2) > b <- c(100, 2, 4) ## error: > log(a) [1] -Inf 0.0000000 0.6931472 ## error, as expected: > cor(log(a), log(b), method="pearson") [1] NaN ## not an error any more (not expected): >

Or at least is seems that way to me. It's not a big problem, but the behavior doesn't match the documentation. (I think r-help is the place to report this. ) > x <- factor(1:5) > x.ro <- reorder(x, rnorm(5)) > is.ordered(x.ro) # should be FALSE according to ?reorder [1] TRUE > > x.ro <- reorder(x, rnorm(5), ordered=FALSE) > is.ordered(x.ro) # should be FALSE

Hi, I am trying to index a number of Spanish language text files, but a large fraction of the files are generating errors like the following... Error: exception 2 not handled: Error decoding input string. Check that you have the locale set correctly however it looks to me like my locale matches the file type. Running the file command on the files returns $ file

Hi, It seems that anti-aliasing in png(type = 'cairo') is not well supported for the point symbols without boarders, e.g. pch = 16. The Cairo package works well, though. You can compare png() with CairoPNG(): png(): http://i.imgur.com/8niB3jX.png CairoPNG(): http://i.imgur.com/FZBJOxm.png f = function(dev, ..., main = '') { dev(...) plot(c(1, 2, 1, 2), c(1, 1, 2, 2),
