Never mind the query regarding setting attributes. I just found the relevant
section in the manual.
The only remaining question is regarding doing string comparisons in sapply
argument below.
Thank you.

I have encountered a more fundamental problem in my data set. I'm using
read.csv, and all the data are imported as character. How do I do a string
comparison in a line like this:
M10[ !sapply(1:10, function(x)666 %in% M10[x,]), ]
Alternately, how do I change the class type on a column in a data frame from
character to numeric?
Thank you very much.
