Hi. Your messages are rather confusing. Well, if you could get correct final data.frame in loop why not just add inside of loop new column(s) by
psT$chr <- i Maybe it is time to read R intro as good source for starting with R. It has about 100 pages, but you can pick as start only pages 2-40 which are basic for data input and manipulation.
