[R] 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
