To whom it may concern, I am very interested in embedding the R functionality in our application. This is a C application that currently runs on Win32, but will also run on Linux in the future. From the material that I have seen, I need R compiled as a shared library to evaluate R expressions from C. Is this correct? If so, can I download this shared library from somewhere? Is there any API document pertaining to this shared library? Thanks for you time, Chad Jenness 763-229-0427 [[alternative HTML version deleted]]

I have done this and it sounded like all that I needed to do is #include <R.h> to get access to R functionality. However, I was getting compiling errors when attempting to make an R function call directly from C, so I did some research, and this is where I saw the reference to needing the libR.so. By just including R.h, does this provide me with the same R functionality as the references that I saw about the libR.so? If so, then I will continue to use this to access the R functionality and use the "Writing R Extensions" manual.

You need to read the correct part of the manual (and you need a manual from R >= 2.1.0). You are writing a front-end, so read * Linking GUIs and other front-ends to R:: as Duncan suggested. Your comments are not at all consistent with what I wrote there.

I have read this section and it appears to be what I am looking for.
