String Cleaning in R down to just letters

so I'm trying to clean strings in R, and I want to be able to clean every string of all of the non-letter elements. I know I can just use gsub to do them individually, but I want to be able to take out all of them (excluding spaces), or if I get it down to just individual character strings with spaces removed, stripping those as well.

For example, if i have an email address as a string vector, "[email protected]", or a string vector of the form ("abc", "123", "abc123"), stripping them should yield "abcgmailcom" and ("abc", "", "abc") respectively. I'm only going to be working with vectors of multiple strings.

Like this?

char <- c("dc2 54üx*","%67{~\\hjkh")
#[1] "dc2 54üx*"   "%67{~\\hjkh"
gsub("[^[:alpha:] ]","",char)
#[1] "dc üx" "hjkh"
