Hi all! I am new to R. I have a table with 291 columns totally. I would just like to extract columns 1 to 5 and columns 243 to 291. I am now able to extract columns 1 to5 separately or columns 243 to 291 separately. But I am not able to extract together columns 1 to 5 and columns 243 to 291. The command which i gave was >datrma[,1:5] >datrma[,243:291](datrma is my object containing the table) Please suggest me a command so that i can extract these columns together. Expecting your reply. Thanks in advance! Regards, S.Dhaarini [[alternative HTML version deleted]]

Hi Dhaarini: You combine all the column indices to a new vector using the function "c" col.indices = c(1:5,243:291) newdat = datrma[,col.indices] Hope it helps, Saroj dhaarini s wrote: > Hi all! > I am new to R.
