R help - Aug 2009 - How to extract row values?

Dear All!
I'm trying to extract one specific row from a data frame without columnnames
being included. I only want a 1-dimensional vector that consists of the specific
data on this row. Here's an example:
existing data:
column names: v1v2v3
Row 1             ab cd ef
Row 2             gh ij kl
Row 3             mn op qr
This is what I want to extract:
ab cd ef 
I do not want: v1v2v3
                     ab cd ef
Thank you in advance
Henrik

Assuming your data.frame has the name "data," you would extract
arbitrary
row n by 

data[n, ]

What you have is a one-dimensional vector.  

I think that you are up against an R default.  You are going to get some names
no matter what you do.  You can always change them using the names() command,
e.g.  names(xx) <- c("a","b", "c") to replace
the v1 v2 v3
