[R] Turning Data Frame Columns into Vectors

[jawbonemurphy]

Hi,

I converted an Excel file into a .txt file "X.txt" with no header (
http://r.789695.n4.nabble.com/file/n3908157/X.txt X.txt ) and imported it
with: 

X <- read.table("/Users/johnlogandurland/Desktop/X.txt", header=FALSE).

What I would like to do is to make the first column into a factors vector,
and then analyze the rest of the columns in the data table using those
factors.  The problem is, I haven't found a way to convert the rest of the
columns into vectors with length = nrows so I can apply the factors vector
to them.

When I try:

vect <- X[1]

I get an object with class "data.frame" and length 1, and the "[[]]" command
seems to turn the column into a "factor" vector, though with the right
length.  This seems like it should be a really easy thing to do, but I've
looked through R-intro and been unable to find a good answer.  Any ideas?

Many Thanks,
Logan
