Re: [R] extract data from a column
So if I am given some data that look like this: > head(CTSS) V1 V2 V3V4 V5 V6 V7 1 chr1 564563 564598 chr1:564588..564589,+ 1336 2 chr1 564620 564649 chr1:564644..564645,+ 94 3 chr1 565369 565404 chr1:565371..565372,+ 217 4 chr1 565463 565541 chr1:565480..565481,+ 1214 5 chr1 565653 565697 chr1:565662..565663,+ 1031 6 chr1 565861 565922 chr1:565883..565884,+ 316 what I would like to do is to obtain two columns from column V4 like: start_coord stop_coord 564588564589 564644564645 I will try and see if it works what you suggested.

Re: [R] extract data from a column
If I understand what you want (which I may very well not) you could use something like this: If this is an example of your type of data: 564589,+ substr(x, 1, 6) as.numeric(x) Please try to post something more thorough if you would like a better answer.
