I am new to R and couldn't find any information on how to handle my table
data that I just read in the way I want to use it..

I read in a table from a file:
x <- read.delim("filenam", header=TRUE)

one column (x$label) hold the class labels. Another holds some values
I want to calculate summary statistics for different classes.

How would I do this?
