[R] Removing

[bad2101 at columbia.edu]

I'm trying to remove the elements "No" from the character vector

Ill=c("No","Yes","Yes","Yes","No","Yes","Yes","Yes","Yes","Yes","No","No","No","Yes","No","Yes","Yes","Yes","No","Yes","Yes","Yes","No","Yes","No","Yes","Yes","No","Yes","No","Yes","Yes","Yes","No","No","Yes","No","Yes","Yes","Yes","No","Yes","Yes","Yes","No","No","Yes","Yes","Yes","No","No","Yes","No","Yes","Yes","No","Yes","Yes","Yes","Yes","No","No","No","No","Yes","Yes","No","No","No","Yes","Yes","Yes","No","Yes","Yes")

but cannot figure out how to do it.  I appreciate any help you have to offer.
