is there a function like %in% for characters?
Or, using the %foo%-style functions: "%charin%" <- function(x, y) regexpr(x, y) != -1
"a" %charin% "asdf"
[1] TRUE
"a" %charin% "bsdf"
[1] FALSE Cheers, Rich

I suppose here's one way:
hasChar <- function(x, y) { length(grep(x, y)) > 0 }
hasChar("a", "abcd")
[1] TRUE
hasChar("e", "abcd")
[1] FALSE Andy
From: Terry Mu like: "a" %in% "abcd" TRUE Thanks.
