Hi, I'm trying to write modified versions of R save/load functions which read from/write to a char array instead of a file pointer. I want to compile my functions into a library and dyn.load them. Of course the new functions mySave/Load will use some of the internal R functions used by save/load, for example "MarkSave" (to be found in .../src/main/saveload.c). I declared them as

Dear All, I am running R version 0.65.0 under a) Suse-Linux 6.1, and Suse-Linux 6.2, compiler gcc-2.95, CPUs pentium pro 200, 128MB, and pentium II 450, 128MB b) Solaris 5.7, compiler gcc-2.95, cpu SUN sparc, 4000MB When I set --nsize to more than 1M, R's internal storage management runs havoc. gc() indicates the requested sizes, but the overall process size is much too big: Running R with

I was hit by ugly crashes of R, when I tried to read big data sets ("volcano"). So I looked into the code and found the following in character.c (triggered by substr()): I assume that the helper function AllocBuffer() shall facilitate an economic memory management. But the use of realloc() in the else-branch does not conform to ANSI and may hit you with certain compilers. When called

I have a vague recollection of seeing a R-function that will output a table or matix in a format suitable for the tabular enviroment in LaTeX. But I cannot find it. Any hints?

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.

I'm trying to debug some C functions I've written for use with R. Until recently debugging them with gdb was no problem. But since I switched to R-1.2.0 (from R-1.0.1) gdb can no longer find the entry points of my functions. It either pretends to set break points but doesn't stop there or it only stops at the end of the function. R version R-1.2.0 gdb version GNU gdb 4.18 gcc version

Hi I try to develop a R interface to a set of C routines, in order to produce a R-package on Geostatistics. My C-code uses interaction with the user as I use printf and gets statements. I develop the code in a LINUX environment and do not face any problem having the questions and answers routed on my current Terminal. When I tried to port the package on Windows, the problems began.

Dear R developers, this mail is basically a summary / clarification of some previous mails I sent to this list last week (subject "Catching warning and error output"). Duncan Murdoch pointed out that these were badly organized, and suggested I repost, collecting the main points previously spread out between several mails. Problem statement: In an application embedding R, I would

Hi there. I'm being asked for a passphrase for a key file that does not exist. See debug output below. Both client and server default to SSH2. Creating a DSA key without a password and copying the public portion to the server's authorized_keys2 allowed me to login w/o a password. I downloaded and installed the latest version of SSH from OpenBSD CVS, and now its asking me for the

I am planing to buy several machines with 2 GB RAM. Is R able to use this much memory?

I have written the following function to calculate the weighted mean difference for univariate data (see http://www.xycoon.com/gini_mean_difference.htm for a related formula). Unsurprisingly, the function is slow (compared to sd or mad) for long vectors. I wonder if there's a way to make the function faster, short of creating an external C function. Thanks very much for your advice. gmd

I maintain the geometry package, which integrates the Qhull C library (http://qhull.org) into R. The Qhull function I hook into requires an open FILE handle as one of its arguments. I had set this file handle to stdout, but now R check NOTEs the presence of stdout, and the CRAN maintainers asked me to get rid of these NOTEs. Including the following defines means the checks are passed on CRAN:

I want to use the replace function on "R_Jeter_04_post" (see attached) so that S=1, D=1, T=1, HR=1, O=0, K=0, E=0, FC=0, and W,IW,and HP are removed, so that i have a simple list of 1's and 0's. I understand that I need to use the command "replace(x,list,values)" and "rm()" but I'm having trouble using them. (syntax errors and whatnot) Any help would be

So is this an expected behavior or is it a bug which should be reported somewhere else? Thanks! Georg? ? ? Gesendet:?Dienstag, 09.

I really don't know. I would call it a request for extended capabilities of [.data.frame, rather than a feature or bug. But maybe wiser heads than mine who monitor this list can sort it out. -- Bert On Wed, May 24, 2023 at 8:52?PM Georg Kindermann <Georg.Kindermann at gmx.at> wrote: > So is this an expected behavior or is it a bug which should be reported > somewhere else? >

Hi, I am writing a function in C that is meant to be called by R. In the C function, I used a gsl function gsl_stats_mean. The code is as simple as below void gsl(double *m, int *dim){ int r, c; r = dim[0]; c = dim[1]; double mean = gsl_stats_mean(&m[0], 1, r); Rprintf("mean = %f\n", mean); } The C code is succesfully compiled and the output is as follows. $ R CMD SHLIB

I've used ssh as a secure telnet up to now but done little else with it. The FreeBSD machines I look after on our internet-facing network all have one account which I connect to for administration. I've set up /etc/hosts.allow on all the machines to only allow ssh from a limited internal network range. Now I want to create a new account on one machine which will be accessible from the
