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
