Create data frame with all possible combinations of vectors x and y?

Question

I have 2 vectors, x and y:

x <- seq(from=21.6, to=22, by=0.01)
y <- seq(from=58.77, to=58.93, by=0.01)

I want to create a data frame df1<-data.frame(x,y) with all the possible combinations of x and y. How can I do this?

exactly what I was looking for. Thanks! – Ignacio Aug 28 '15 at 19:06 — Ignacio, Aug 28 '15 at 19:06

We can use expand.grid to get all the possible combinations between the two vectors.

expand.grid(x,y)

and of course simply wrap it in `as.data.frame` to get your desired format – MichaelChirico Aug 28 '15 at 19:12
Not "of course". `?expand.grid` . It returns a dataframe. – IRTFM Aug 29 '15 at 01:37
