A newbie question: assume that I have for example 30 columns in my

Sara,
You didn't read your data into R correctly.
If your data are really in the form you posted (one long column
of mixed data types and lots of blank lines), then I would:
1. remove the blank lines with my text editor and save (say, mydata.txt)
2. scan() the variable names into a vector

I wonder how did you created your arguments?

You might want to consider the use of 'attr' to assign attributes to an
object. That way you can keep your object as a data.frame:

Hello all,
I've had trouble converting a data.frame to a matrix (numeric) using either
data.matrix() and as.matrix().
After executing one of those I end up with another data.frame with only the
first column of the original data.frame.
I use a window (tcltk) to let the user choose the columns he wa

the docs or FAQ for this.
Since there are no "BM" in the mtrs data.frame, but only in the "parent"
data.frame (trees), I'm assuming the subset data.frame is still associated
with the original. Is that correct and how woul

I think data.matrix() is what you want.

But read.table function returns the data.frame object.
What is the way for conversion of the data.frame object into matrix
