...for debugging this. I'm starting to put print statements into the R code, and into the C code in R (src/main/optim.c), but it hasn't shown me the source of the problem. Thanks! Here is the code I'm using to initialize: putenv("R_HOME=/apps/R/install/lib64/R"); const char *R_argv[]= {"RInterfaceTest", "--gui=none", "--no-save", "--no-readline", "--silent"}; Rf_initialize_R(sizeof(R_argv)/sizeof(R_argv[0]), const_cast<char **>(R_argv)); setup_Rmainloop(); ParseStatus status; SEXP cmdSexp, cmdexpr = R_NilValue; int err...

Hi, I had a quick question I was hoping someone might be able to answer, as my journey through the source code so far has not been very profitable. I have a command line program that embeds R, and the program works just fine when run from the command line. However, when I run the program as a job in the LSF cluster at my institute, the following error occurs: Fatal error: you must specify

Hi, I am considering if I should invest in learning R. Based on the language definition and introductory documents, it seems nice. But now I am faced with a problem: I want to be able to run R programs easily from the unix shell, and write scripts that can automatically select R as the interpreter: #!/usr/bin/R cat("Hello world.\n") This of course doesn't work, because /usr/bin/R
