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

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

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

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)%>'}" >

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.

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

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

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, ?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!");

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,

Hi, The C function PrintWarnings is currently not in the C API, but it is declared non static in the svn trunk as of revision 53110 . As this is the only function that creates the last.warning object used by the R function warnings(), I think it would be useful for programs that embed R to be able to call it. So, will it remain non static, that is callable although it's not declared in the

Hello, The use of .Call and the like all depend on loading shared libraries and registering routines from it. Also, .Primitive and .Internal depend on routines being registered in the R binary. And applications that embed R can override routines declared in Rinterfac.h, but is there a way for an application embedding R to register other routines defined in the application without loading a
