Dear R users,
Suppose I have an vector like this:
animal <- c("Tiger","Panda")
I would like to know is there any function that check for the
existence of certain item in a vector.
e.g.
> func("Tiger",animal) # check for the existence of "Tiger"
TRUE
> func("Acacia",animal) #Acacia is not an item of the animal vector
FALSE
I know that it can be done by for loop. But I would like to know is
there any built-in function for that.
Thank you very much.
