Hello! I have a matrix: > dim(data1) [1] 34176 581
of 34176 rows and 581 columns, I want to make a new matrix data2 by taking the 2nd column, 9th column, 16th column.... the column number is in the order of: 2 9 (2+7) 16 (9+7) 23 (16+7) ... the new matrix data2 should include 83 columns, is there an easy way to do that using cbind() function? Thanks a lot!
