Why in toupper() concatenating my column when I use it? I am trying to change
the case of a column in a dataframe to upper case...

> seedlings
  Plot Transect SppCode Count
1 M072        2    abco     9
2 M072        1    abco     7
3 M072        1    psme     1
4 M072        3    abco     9
> seedlings["SppCode"] = toupper(seedlings["SppCode"])

And I get...

> seedlings
  Plot Transect                           SppCode Count
1 M072        2 C("ABCO", "ABCO", "PSME", "ABCO")     9
2 M072        1 C("ABCO", "ABCO", "PSME", "ABCO")     7
3 M072        1 C("ABCO", "ABCO", "PSME", "ABCO")     1
4 M072        3 C("ABCO", "ABCO", "PSME", "ABCO")     9

Not what I want. Suggestions?

Thanks,
MVS
