[R] How do I extract single entries from a factor?

[Aditya Singh]

Dear Boris and R-Experts,

I have a variable my_state which is a 2-letter character string telling which American state the user inputs. This I am do a if(identical(database entry,my_state)) to check for occurrences in the database.

The problem is that the database entry[i,j] shows as a factor with various levels, e.g. the output when I do class(database[i,j])is:

[1] "TX" 
AL.. levels through WY

How do I convert a factor into a character?

Aditya

Seems to me you probably wanted a "while" in line 4.

N.b.  There's also a missing "}" and totally messed up formatting :-(
