[R] Splitting a string expression into components

I have a vector of strings that contain mathematical expressions. E.g., x <- c("5 <= 7", "z = 1+2") and I would like to decompose each expression into its left- and right-hand-side components etc., output something like "5" "<=" "7" "z" "=" "1" "+" "2" Is there something built into the R language
