[R] Using paste to create and evaluate a variable expression

Is it possible to use paste to write out an expression and evaluate it? Suppose I want to add two vectors X1 and X2, defined as follows: X1 - 1:6 X2 - 6:1 If I write the following it looks like what I want but is a character: noquote(paste(paste(X, 1, sep = ), paste(X, 2, sep = ), sep = +)) Is
