[R] ggplot faceting like lattice | variable

[stephen sefick]

I would like to be able to do the xyplot in ggplot below.  I read in
the archive that Hadley was working on this for the next release, and
I can not find the documentation (Aug. 23rd).

River.Mile <- c(215 ,202, 198, 190, 185, 179, 148, 119, 61)
Cu <- rnorm(9)
Fe <- rnorm(9)
Mg <- rnorm(9)
Ti <- rnorm(9)
Ir <- rnorm(9)
r <- data.frame(River.Mile, Cu, Fe, Mg, Ti, Ir)

z <- melt.data.frame(r, id.var="River.Mile")

#this is what ggplot does
qplot(River.Mile, value, facets=(variable~.), data=z)

#this is what I would like to do
xyplot(value~River.Mile | variable, data=z)

Thanks

so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
