This was asked recently on R-help. You are calling update.packages() wrong:
The first argument it expects is lib.loc, which is the directory where the
packages are to be installed. (You can see that either from
?update.packages or args(update.packages).) You shouldn't be calling
update.packages() with package names.
install.packages("locfit") is probably what you really want to do.
