I am attempting to construct a conditioning plot with a pair of boxplots within each panel. The resulting plot has panels misplaced. One misplaced panel is on top of the subcomponent describing ranges of the conditioning variable. This is what I did:
X <- cut(rnorm(200), 2)
Y <- runif(200)
Z <- rnorm(200)
given.Z <- co.intervals(Z, number = 4, overlap = .25)
coplot(Y ~ X | Z, given.v = given.Z,
panel = function(x, y, ...){boxplot(y ~ x)})
Any suggestions as to why this does not work and what the correct specification is would be greatly appreciated.
Not sure, but you might want to try boxplot(y ~ x, add = TRUE).
When I did this I had to add xlim = c(0, 3) so the boxplots were drawn completely within the panel.
