Hello everyone, I met a strange problem when I call R expression from C++, here is the details: I edited a function eval_R_command(); double eval_R_command(const char *funcName) { SEXP exp,e; ParseStatus status = PARSE_OK; int i,n; double val; PROTECT(exp=NEW_CHARACTER(1)); SET_STRING_ELT(exp, 0, COPY_TO_USER_STRING(funcName)); PROTECT(e = R_ParseVector(exp, 1,

Full_Name: R Embedder Version: 2.7.2 OS: win XP SP 2 Submission from: (NULL) (83.25.35.249) I'm having problems using embedded R. I try to adapt examples from "tests/Embedding/". Everything works fine except when I try to reinitialize R for the second time in the same program. I need to reinitialize correctly because my code is some kind of .dll plugin to an external application.

Good morning! After I changed some permissions and owners of some files where Rowland told me, I have the next escenary: [root at proxy ~]# systemctl status named.service ● named.service - Berkeley Internet Name Domain (DNS)    Loaded: loaded (/usr/lib/systemd/system/named.service; enabled; vendor preset: disabled)    Active: active (running) since Mon 2018-06-11 08:54:10 AST; 12min ago  

I'm very green with R, so maybe this is not a bug, but it looks like one to me. The following program segfaults at the second call to Rf_PrintValue(). To failure depends on the value of the y-string. E.g., if I change it from "coverage" to, say, "COVERAGE", the segfault does not occur. /* bug.c */ #include <stdio.h> #include <Rinternals.h> #include

Dear friends, I am trying to create a web application to produce some statistical result using R.

I forgot to say that  I updated Centos from 7.4 to 7.5, and I updated samba4 to the new version. This Would be a problem of records of something like that.

Hi everyone. I'm trying to learn my way around the R internals. I've gone pretty much as far as I can go with the information given in Writing R Extensions and R Internals, but I still have a lot of questions, too many in fact to post them to the r-devel list. But I think I could answer many of these if I could just step through R's execution during some basic operations. What

Hello, I created a library for a bunch of functions that I use frequently so that I dont have to carry duplicate copies around to wherever I fire up an R sesssion. However, I have problems locating the help files for those functions. Here are some details. I created the library "myR" and installed this in /home/royle/R using: R INSTALL -l /home/royle/R /home/royle/Rpackages/myR

Dear r-devel list members, It's been several years since I last built a custom Windows installer for R, and despite my notes and the instructions in Sections 3.1.7 and D.4 of the R Installation and Administration Manual, I've run into a problem, receiving the following error message: ----------- snip ----------- C:\R\src\R-2.11.1\src\gnuwin32\installer>make myR

Hi the list, Some rumour (!) say that is it possible to prepare some tests for checking our code using .Rin and .Rout. It seems to be a very good practice, but I did not manage to find information on it. So does someone know how it works ? What are we suppose to write in Rin ? More precisely : - I have a package myPack.r in directories ~/myR/myPack/R/ - I create the directory

I also have several packages in my RW0633 in Windoze and I would like to keep them in one place when I update the R system.

This is definitely tangential to the list: I'm on Ubuntu (22.04.2 LTS) not Debian and I'm sure this is about issues in the Ubuntu package management on my machine, R is only revealing them. The original subject line came from me wondering if my going over to the r2u repository would solve the problem.? However, as I think Dirk said, that's only really likely to be answered by trying

Hi, I'm trying to conduct sensitivity analysis in R using the 'sensitivity' package. Although the description of functions seem straightforward, I can?t succeed.
