search for: r_char

Hi, I am trying to study R internal behaviour. So long, I have not succeeded to access the value of R strings from C. I use: void salvesta_tabel( SEXP data_frame, SEXP file ) { printf( "nimi %d\n", (R_CHAR)( file)); } and from the R side: salvesta.tabel <- function (x, file = "") { .Call( "salvesta_tabel", x, file) } When calling from R as salvesta.tabel( x, "file") R always crashes while printing the %d part. So I assume that the function R_CHAR is not...

...something I'm doing incorrectly. I've been using this code for months now, and added another column to the type definition, which seemed to break something. Does the following indicate that libR.dylib is causing this crash?

Hi R-devel, I'm trying to get R 3.2.1 working on Haiku (an open source OS inspired by BeOS, not Linux based) on i586. With a few small changes to library paths and ifdefs I am able to get a seemingly working R binary. The build process stops with the 'tools' package. The last lines from make are below. Does anyone have any tips? I'm rather new to debugging at this low level. Are
