This should be an easy one, but I haven't been able to figure it out, x<-c(2, 4, 6, 9, 10) #how do I remove a single value x<-x[-2] # will remove the second element of the vector not the number 2 This is part of a loop that looks a little like this... x<-c(2, 4, 6, 9, 10) remove.value<-4 #then I need to remove the value returned by the loop.
