Sounds good.

Hi all
Thanks for the replies. After some testing it seems like I dont need the
unsigned stuff and the functions seems to work fine with just a regular
int variable. The functions I wanted to use were just small parts of a
program and in that program bitmap images were loaded and image data

Touche, but for all uses I hav
Hi,
that's not going to fly.
A CharacterVector holds strings of arbitrary lengths, well technically it holds
other R objects (SEXP) that hold pointers to strings.
A RawVector holds unsigned char.
Can you add some meat to your example, e.g. what you'd expect to go in, etc ...

Hi
Im trying to use some C++ functions in R. However, these functions are
build around unsigned char* variables (1D array). I have for example a
large matrix in R that represents black (e.g. 1-bit image, 0 and 1s). I
cant find a solution to convert a character vector into unsigned char*
within
