R help - Oct 2012 - Help with toupper()

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
