[R] passing a string to expand.grid

Hi R-Users,

I'm having a problem with strings.

My string looks like this "c(-1,1), c(-1,1)" and I would like to pass
it
to expand.grid so that expand.grid(c(-1,1),c(-1,1)) will be done.

Cheers,

Thomas

[R] passing a string to expand.grid

Try this:

x <- "c(-1,1), c(-1,1)"
eval(parse(text = paste("expand.grid(", x, ")")))
