hi, i am from the pharma sector doing my M.S.(Pharm). and i am working on the software development for QSAR studies. For this C++ codes for descriptors calculation of chemical compounds has already been written, which gives output as excel file. Now my task is to make a QSAR model by selected the important descriptors using correlation and regression methods using R codes. I know very well about these if i want to compile it with R software. But the main problem is to run the R compiler in background automatically and to execute R codes with the different front end (visual studio based), So how is it possible to use both C++ as well as R codes in continuation, by using the data output from C++ codes as input for R without using R compiler in front. Waiting for the response.............. Thanx -- *Naveen Verma,* *Department of Pharmacoinformatics,* *NIPER Mohali (Punjab,India)* [[alternative HTML version deleted]]
