[Rd] Embedding R in C application
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?

Re: [Rd] Embedding R in C application
I have done this and it sounded like all that I needed to do is #include 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 want to look at the "Writing R Extensions" manual, in particular the chapters on the R API (for access to the underlying computational routines) and the one on linking GUIs or other front-ends (which sounds more like what you want to do).

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

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.

Re: [Rd] Error in compiling R
Thanks, I got this resolved. Now to embed the R.dll into a C application, do I need to compile R with any shared library flags set?

Does > anyone have any suggestions? Yes, it seems you have corrupted the files during unpacking. Did you use the version of tar in the Rtools.zip? Whatever you used to unpack the files has changed LF to CR line endings. Winzip is notorious for doing things like that. Only a very few tools will unpack that tar file (which contains symbolic links) correctly. Which is why we provide one, and issue a warning in the R Installation and Administration manual. > -- Making package datasets > adding build stamp to DESCRIPTION > installing R files > installing data files > preparing package datasets for lazy data loading > Error in load(zfile, envir = envir) : input has been corrupted, with > LF replaced by CR > Execution halted > make[4]: *** [lazydata] Error 1 > make[3]: *** [all] Error 2 > make[2]: *** [pkg-datasets] Error 2 > make[1]: *** [rpackage] Error 1 > make: *** [all] Error 2 > > > Thanks, > Chad Jenness > Electronic Payment Business Services > Office: 612-667-9782 > Email: [EMAIL PROTECTED] > > "This message may contain confidential and/or privileged information. > If you are not the addressee or authorized to receive this for the > addressee, you must not use, copy, disclose, or take any action based > on this message or any information herein.

[Rd] Linking C/C++ GUI to R.dll
Hi, I am in the process of linking a C/C++ application to the R.dll directly. I have obtained the R source code and compiled it successfully. I have also successfully linked the R.dll directly into our application and have made calls successfully into the R.dll that are included in the sample rtest.c and in the "Writing R Extensions - The R API". The R functionality that we are interested in embedding into our application is the data analysis and graphics. However, I did not see any references to this in the R API section of the documentation. Is this functionality available from our C/C++ application via the R.dll? If so, how do we access this functionality?
