[R] trimming a factor

[Dan Chan]

Hi, 

I have the following dataframe.  The County Column has many empty spaces
at the end.
I want to cut out the empty space and put them back into the dataframe.
How can this be done?  

> head(DailyCounty)
                 Date               County GFCPer GFCEquip Acre nFires

>sub(' +$','',levels(DailyCounty$County))
"Appling" 

>sub(' +$','',DailyCounty$County)
[1] "1"

Thank you!
