R help - Apr 2010 - Formatting data, adding column names, use reshape, a newbie question

Hi all,
I'm an R novice.

I have data that's already formatted as "molten" that reshape
should be able
to work with. For example, the following was read in with
read.csv(filename,sep=" ", header=FALSE)

      V1               V2         V3                 V4
 V5
1    original    book    book.source1.txt    328900494    3039.525
2    original    book    book.source1.txt    328900494    3057.952


I would like add column names so I can use reshape's cast method.

How do I go about that?

Thanks,
Paul

names(df) <- c("col1", "col2", ..., "col5") ?
