No no no.

She (apparently) says she wants to plot a numeric grid given the x and
y coordinates of the grid, not create a character matrix of strings
representing the ordered pairs.

set.seed(1234)
x <- runif(6)
y <- runif(5)
dat <- expand.grid(x=x,y=y)
plot(y~x, data = dat)


However, if what she really means (??) is that she wants to plot
values in some way AT the coordinates, then she probably needs to look
at ?contour or ?image (or their lattice or ggplot equivalents).

Cheers,
Bert
