Hi,
I am extremely new to R, and was wondering if someone would be able to help me
with a question regarding the expand.grid function. When I input
expand.grid.rep <- function(x, n=1) do.call(expand.grid, rep(list(x),n))
expand.grid.rep(c("a", "b", "c"), 3)
my output is as follows,
Var1 Var2 Var3
1 a a a
2 b a a
3 c a a
4 a b a
5 b b a
6 c b a
7 a c a
8 b c a
9 c c a
10 a a b
11 b a b
12 c a b
13 a b b
14 b b b
15 c b b
16 a c b
17 b c b
18 c c b
19 a a c
20 b a c
21 c a c
22 a b c
23 b b c
24 c b c
25 a c c
26 b c c
27 c c c
I was wondering if there was anyway I can change the row numbers to labels that
indicate what is in each row. Instead of a 1, I'd like to have a label saying
"aaa", etc. I'm not sure if this is even possible within the expand.grid
function but any help would be appreciated. Thanks.
