[R] Column notation

[rajaa at uchicago.edu]

Hello,

I would like to run a correlation on values in a table that
has 4 rows and 136 columns. However, I am only interested in
correlating the values in alternating blocks of 15 columns.
For example, I would like to correlate the values in row 1,
columns 2-16:31-46:61-76:91-106 with values in row 2, columns
2-16:31-46:61-76:91-106.

Is there a way to notate this in the cor command so that the
function will specify nonsequential values from the table? 

Thanks for any help.

Sincerely,

Anjali
