yes, I know that there is... ;-)
but probably you wanted to ask another question :-)

I'm pretty sure you haven't tried ?svd aka help(svd),
nor other things that are much recommended *before* asking the
2000+ readers of R-help.

It may really make much sense for you to learn how to get help
from R's builtin documentation systems.
Probably you should also take time to read the
"Introduction to R" manual that is almost surely part of your R
installation, and is additionally available from the R project
web pages.
