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!

Allen
