I have to admit that I am not a fan of R, and I explained things also bad with complicated data collections. Working with this guy after one day, then I feel more comfortable with R. He not also listened very patiently my bad explanations but also coded with me. I highly recommend him and hope that we will collaborate next time if we have a chance.
