The data set for "combined" is pretty huge, but a few columns looks like
this, so just picture it with 187 columns:

miceSample may be just the last 2 columns (or whatever sample R comes up
with) vsa_don vsa_hyd or looking at my code from my original post, it's
"nvars"
It looks like that code did it perfectly. Thanks.
