[R] test if text is part of vector

Hello, this is a very simple question: How can I find out if a word is part of a list of words like: a - word1 b - word4 vector - c(word1,word2,word3) I tried it with match(a,vector) but this gives the position of the word. I am not sure if and how that can be done with a logical operator

You also might look at grepl() if you have time: it allows regular expressions and will be a little (a lot?) more flexible in how you define a match if you want to ignore things like capitalization. (mnemonic: the L in grepl indicates its like grep but returns logicals instead of positions)
