[R] Multiple Hexbinplots in 2 columns with a Single Categorical Variable

[Paul Murrell]

Hi

Does this do it ... ?

useOuterStrips(hexbinplot(Transferin ~ Age | factor(Race) + factor(Sex),
                           data=NHANES, type="r",
                           aspect=1,
                           scales=
                           list(x=list(relation="free", rot=0,
                                  at=list(TRUE, TRUE, NULL, NULL)),
                                y=list(relation="free", rot=0,
                                  at=list(TRUE, NULL, TRUE, NULL))),
                           par.settings=
                           list(layout.heights=list(axis.panel=c(1, 0)),
                                layout.widths=list(axis.panel=c(1, 0)),
                                par.strip.text=list(cex=1))))

In this example, the 'relation="free"' is not doing much, so a simpler 
version would be just ...

useOuterStrips(hexbinplot(Transferin ~ Age | factor(Race) + factor(Sex),
                           data = NHANES, type = "r",
                           aspect = 1,
                           scales = list(alternating=1, tck=c(1, 0))))

... but it sounds like that might not be appropriate for your real problem.
