R users,

I am trying to find some way to find the value of a column that is repeated
the most for each StandID of a dataframe.  I have research methods online
and the help page, but have had no success in finding a solution.  I have
tried using the table function but it returns items for the whole dataset
and not by the StandID.  Any help will be appreciated.  Thanks in advance.

R version 2.11.1
Windows 7
Dataframe is imported from text file

StandID     PlotNum    HerbNum      Woody
001            1               1                    low
001            2               2                    medium
001            3               1                    low
001            4               3                    low
001            5               1                    high
001            6               2                    medium
002            1               1                    high
002            2               2                    high
002            3               2                    low
002            4               3                    high
002            5               1                    high
002            6               2                    medium

I would like to get the following from the dataframe

StandID    HerbNum      Woody
001          1                    low
002          2                    high

Thanks,

Randy
