[R] plotting vectors of different lengths

[arun]

Hi Eliza,
You could also do:
res <- outer(y,x, FUN=function(u,v) paste0("(",u,",",v,")"))
 dimnames(res) <- list(y,x)
#or
 names(x) <- x
 names(y) <- y
 outer(y,x, FUN=function(u,v) paste0("(",u,",",v,")"))
A.K.

You are welcome, Eliza.

If I understand correctly, the following will do:

x <- 1:8
y <- 1:5
matrix(apply(expand.grid(x = y, y = x), 1, function(r) paste0("(", r[1],
",", r[2], ")")), ncol = length(x))

Best,
Jorge.-
