Hello there, I recently wrote some code to perform pairwise correlations between all samples in a large dataset. So we are talking about performing pairwise correlations between 400K vectors. Since R has a very rich library of functions, it was very easy to code this in R. However, R was probably not the best choice as it is super slow for this large job. So my plan is to recode it in C. I was wondering if it is possible to see the code between some of the functions.
I am looking for the raw code for simple data handling functions such as split, cut, etc so that I can directly use those in C. I am fairly new to programming in C and so this will be a big help. Thanks for you help in advance.
