[R] Multiple line commands in R scripting

[R] Neat conditional assignment

I would like to make a new vector with values taken from two existing vectors conditional upon a third. At present I am doing this with a for loop but wonder if there is not a neater way, given some of the very neat things R can do. a<-rep(c("A","B"),50) b<-rep(1,100) c<-rep(2,100) a is thus "A"
