 [1] 79.63 79.63 79.63 79.63 79.63 79.63 79.63 79.63 79.63 79.63

You have asked several introductory R questions today, suggesting you
are a new useR. This basic material is covered in the documentation
provided with R or available from the R Website. I suggest you start
with 'An Introduction to R':

http://cran.r-project.org/manuals.html

The first 30 or so pages of which describe the major pieces of basic R
usage. Far more efficient to consult the docs than to wait for a
response from the list, even if the response time on R-Help is
generally /very/ quick!
