Hi,
May be this helps:
Var1 <- LETTERS[1:3]
Var2 <- 1:2
do.call(paste0,expand.grid(lapply(VarNames,get)))
#[1] "A1" "B1" "C1" "A2" "B2" "C2"
A.K.

I have a list of variables of a variable length (e.g., Var1, Var2, Var3,
... Vark). What I want to do is somehow feed that information into the
paste function, like:
paste(Var1, Var2, Var3...)
The problem is that I don't want to hard-code it because it's wrapped
within a function. Is there a way to supply a string? e.g.,
k = 2
VarNames = paste0("Var", 1:k)
paste(someFunction(VarNames), collapse="")
Suppose Var1 = A, B, C and Var2 = 1, 2. The result should return A1, A2,
B1, B2, C1, C2.
I've tried using eval, and get, but with no luck. Thanks in advance!
