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 there a way to tell R that I want to evaluate the text, not just print
it out as a character?
