You can try the following:

 a == grep("ear", a, value=T)

Subject: [R] simple q: returning a logical vector of substring matches

I'm a relative R novice, and sometimes the simple things trip me up.

Suppose I have

a <- c("apple", "pear")

and I want a logical vector of whether each of these strings contains "ear" (in this case, F T). What is the idiom?

Quizzically,
Mark Lindeman
