Is this possible? For instance, I have a function that returns a vector length 3. In one statement I'd like to assign each element of the vector to different variables. Syntactically, I hoped this would work: c(x,y,z) <- myfun(); Thanks, -- Jeffrey Horner Computer Systems Analyst School of Medicine 615-322-8606 Department of Biostatistics Vanderbilt University

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, I think I've found a bug in the C function do_grep located in src/main/grep.c. It seems to affect both the latest revisions of R-2-13-branch and trunk when compiling R without optimizations and with it's own version of pcre located in src/extra, at least on ubuntu 10.04. According to the pcre_exec API (I presume the later versions), the ovecsize argument must be a multiple of 3 ,

Hi, I'm trying to create a package that contains reference class definitions from which users can create reference objects, but there seems to be something awry.
