R was working fine for a while.

Hello, I would like to annotate a graph with the expression 'alpha = 5%' (the alpha should be displayed as the greek letter). I tried > text(1,1,expression(alpha == 5%)) which gives a syntax error. escaping the percent sign (\%) or doubling (%%) does not help. What do I do?

Hi, Im using R 2.1.1 and running Code that previously worked (on R 2.1.0 I believe) using the 'timeDate' function from the fCalendar package. The code now throws an error: Error in if (Sys.timezone() != "GMT") warning("Set timezone to GMT!") However I have read the documentation of the fCalendar package and I have set my system variable TZ to GMT. I tracked the

Hello, Im running R 1.8.1 on Win2000 and frequently using the function history() to keep track of what I did in my R session. In a recent session I typed history(max=Inf) and to my surprise there were only 15 lines of code where there should have been approx. 300 lines and I lost a lot of valuable work. Do you have any idea what caused this behaviour? help(history) didn't make me any

I'm trying to build an RPM of R 2.3.1 on a very old RedHat system (specifically, a ROCKS 3.3.0 cluster which is built on RH enterprise 3 (I think??)) I downloaded R-2.3.1.tgz from CRAN; downloaded the R.spec file cran.r-project.org/http://cran.r-project.org/bin/linux/redhat/SRPMS/ ; and ran rpmbuild -ba R.specs. Everything goes along fine until ... make[5]: Entering directory

I tried to compile R (current R-patched to be more precise) with gcc 3.5 by Apple (which will be probably shipped with Tiger) and here's how far I got: 1) compilation itself was fine except for one exception: ../../../../../../R-patched/src/library/stats/src/starma.c: In function `forkal': ../../../../../../R-patched/src/library/stats/src/starma.c:384: error: invalid lvalue in

Dear all, i have noticed some strange behaviour in the ?jitter? function in R. On the help page for jitter it is stated that "The result, say r, is r <- x + runif(n, -a, a) where n <- length(x) and a is the amount argument (if specified).? and "If amount is NULL (default), we set a <- factor * d/5 where d is the smallest difference between adjacent unique (apart from fuzz) x

Hello. I've got two values which are calls (i.e. LANGSXPs). The first one, x, is generated through the parser of gram.c. The second one, z, is built manually, by retrieving the symbols of "str" and of "lm" via the install function. The structure of x and y are shown at the bottom of this email. Evaluating x succeeds: > # R.Raw.eval_langsxp x;; > function

Hi, I'm trying to document a data frame in Rd format. The data frame contains a variable called 'Health_Env'. When I create a template for the Rd file using 'prompt()' the variable name is included as-is and when I run R CMD CHECK I get a latex error because latex considers '_' a special character (used for subscripts) which is only allowed in math mode. When I

Hi, How can I specify which functions should be exported when I build a shared library with 'R CMD SHLIB foo.c'?? I tried putting a file named foo.def in the same directory with the line 'EXPORTS' and the names of the functions to be exported, but the file is deleted in the build process. Any help is appreciated, Martin Keller-Ressel

Hi, I want to call R from Perl to generate plots to be displayed on a webpage. What I found out so far is that there is a package called RSPerl on www.omegahat.org which should do what I need. However in the description it says it has been tested with R 1.3.* the latest. I'm using R 1.8.0 right now so the package seems rather unmaintained. It is not easy for me to just install it and see
