Hi, Is this sufficient? if (.Machine$sizeof.pointer==4){ cat('32\n') } else { cat('64\n') } Or is it better to test something in R.version, say os? I'd like to use this to specify appropriate linker arguments when building the RMySQL windows package. Jeff -- http://biostat.mc.vanderbilt.edu/JeffreyHorner

In R-2-4-branch r39548, Rcons_vprintf is called from stdout_vfprintf when R_Outputfile is NULL. When called and output is greater than R_BUFSIZE, output is truncated to R_BUFSIZE. Here's a one-line fix: Index: src/main/printutils.c =================================================================== --- src/main/printutils.c (revision 39548) +++ src/main/printutils.c (working

I made sure that the implementation passed 99% of the tests, however there were two that gave differing results which I think are related to traversing hashed

Hello all, I've been working on a new R Graphics device that targets Adobe's Shockwave Flash format (SWF for short). It uses http://www.libming.org/ on the backend. Here are some example outputs so far: http://160.129.129.41/~hornerj/plots/ Once you click on the above, choose a directory like 'smooth' and then click on test.html to see a side-by-side comparison of the swf

A professor here at Vanderbilt sent me the following code. Each of the text strings should right justify against the center vertical bar, but because of font issues it doesn't. I understand that there are workarounds, but I was just curious if this was consistent across all platforms. On linux with R 2.7.1 and R-trunk (r46103), both acrobat reader 8 and kpdf render it incorrectly. How

Hello, I've been wondering why my no-optimization R-devel builds have been hanging during "building/updating package indices ...". I tracked it down with gdb to this line from do_basename in utils.c: while ( *(p = buf + strlen(buf) - 1) == fsp ) *p = '\0'; Now, imagine if your compiler places the variable fsp immediately before buf on the stack, and strlen(buf) is 0.

I was writing Rd documentation for a new package when I came across this issue. Here's the smallest example: > library(tools) > cat("\\examples{x <- '<%=rnorm(1)%>'}\n",file=file.path(tempdir(),'test.Rd')) > readLines(file.path(tempdir(),'test.Rd')) [1] "\\examples{x <- '<%=rnorm(1)%>'}" >

Byron, I just read your blog (statcomp.blogspot.com, linked from your other post) and rand across your idea of an R/Flash graphics device. I've also been giving this some thought because of this amazing interactive flash app: http://tools.google.com/gapminder and others from http://www.gapminder.org/. I would love more than anything to work on this. The only hitch is that I'm so

I'm currently working on embedding R into the Apache2 webserver (with some positive results...), but I'm struggling to identify the best way to expose the apache data and functions to R. A couple of thoughts: In light of the recent discussion on "S3/S4 classes performance comparson", I'm leaning toward implementing the interface with S3 style classes. I appreciate

Hello, ?DateTimeClasses states that "one can add or subtract a number of seconds or a 'difftime' object from a date-time object, but not add two date-time objects." So, is the below expected behavior? > x <- Sys.time() > x [1] "2007-02-21 16:19:56 CST" > x + as.difftime("1","%H") [1] "2007-02-21 16:19:57 CST" Warning

For embedded projects, one may want to eliminate the per-session temp directory created by InitTempDir() and just use a system-specific temp directory. Here's my solution: extern char *R_TempDir; void my_InitTempDir() { char *tmp; if (R_TempDir){ if (rmdir(R_TempDir) != 0){ perror("Fatal Error: could not remove R's TempDir!");

I'm interested in easing my way into learning VIM by first using the Cream text editor, liking the idea that it will work on both my Linux and Windows computers. I've installed Cream on my Linux machine, but can't figure out how to make Cream talk to R? Does anybody know? I'm using Ubuntu if it makes a difference. Thanks. -- View this message in context:

Hi all, We have a user that would like to create pdf plots using the Arial font. One way for her to do this is to use the Cairo graphics device which produces pdf's beautifully and embeds fonts automatically. She could also install the msttcorefonts package from ubuntu to obtain the Arial font. The problem is that she is using Sweave() to produce a document that contains the pdf plots,

Section 4.3.4 of R-lang.texi version 41191 in the paragraph that starts "When h(3) is..." explains that x and y are unbound variables in the function body of g in this example: f <- function(x) { y <- 10 g <- function(x) x + y return(g) } h <- f() h(3) while the paragraph following the example explains that "bound

Hi, Here's a patch to the readChar manual page (R-trunk as of today) that better clarifies readChar's return value. It could use some work as I'd also like to add some text about using nchar() to find the length of the string that readchar() returns, but I'm unsure which of type="bytes" or type="chars" to mention. Is it type="chars"? Index:

Hi all, I'm setting up a development environment on Windows as the subject implies.

Hi all, I've constructed the following function to test whether or not an object was created from a reference class: isRefClassObject <- function(x) isS4(x) && is.environment(attr(x,'.xData')) && exists('.refClassDef',attr(x,'.xData')) but I'm unsure if it's a complete test or if there's a better way to test. Regardless, It would be
