Hi
I am trying to read a data frame from a text editor in to R. I want some
of the columns to be read in as "character" not numeric.
I figured that I can do that by using "colClasses" in "read.table"
command. However, I couldn't find out how to use "colClasses". e.g. say I have 5 column in the data file. I want 1st and
3rd column to be read in as character. How can I define
this using colClasses? (or is there a better way to do what I want?)
Thanks.
