k = c(1:9)
if( length( which(k==3) ) ){ print("contained") }else{ print("not contained") }

is therre a simple way to test if a vector/list contains a particular value?

for example an operator, along the lines of: ==

more generally, is the a documentaion page that lists/describes all such operators?

lastly, if you didn't know the answer to my question, how would you have gone about searching for an answer? I tried RSiteSearch() using various terms, and I opened R-2.1.0/library/base/html/00Index.html and searched for various terms.

TIA
