[R] Need Help with Manipulating Columns

[cavalier33901]

I have uploaded the property data from Lee County Property Appraiser into R,
but my problem is that I am unable manipulate and use many of the columns
because they are classified as factors.  I think this is because the values
represent selling prices and therefore have $ in front of them.  I tried
using as.integer but this funtion converts the values into a totaly useless
form.  Is there a way to convert these columns from factors into something
usefull for plotting and graphing such as integer form? Thanks 

Will
