heatmap

Hi stackoverflow-pros,

I need your help again :)

I wrote an R script, that generates a heatmap out of a given tab-seperated txt or xls file. At the moment, I delete all columns I don't want to have in the heatmap by hand in the xls file. Now I want to automatize it, but I don't know how :(

The interesting columns all start the same in all xls files, followed by an individual name:

xls-file 1: L1_tpm_xxxx L2_tpm_xxxx L3_tpm_xxxx

xls-file 2: L1_tpm_xxxx L2_tpm_xxxx L3_tpm_xxxx L4_tpm_xxxx L5_tpm_xxxx

Any ideas how to select those columns?

Thanking you in anticipation, Philipp
