Dear Ladies and Gentlemen,
I have a fairly large database (N=13,000) and a single main categorical
discriminator between the groups.
I want to look at the time course of a number of continuous biochemical
variables over chronologic age.
Therefore I believe I need to prepare hexbinplots in two columns with simple
regression lines in them (with useOuterStrips (in library(latticeExtra) if
possible) and also single hexbinplots with two regression lines
(panel.lmlines) corresponding to the two groups to facilitate data
comparison.
Tick marks and labels should be off in most panels, and the scale in each
row will be different.
I have some code written for the NHANES dataset in library(hexbin) which
almost does this job, but leaves blank paper up the middle of the two
columns of panels.
I have been exploring lattice for this which almost gets me there but not
quite.
The code I have written is as follows.
I would be ever so grateful for any advice anyone may be able to offer.
With best wishes,
Stuart Reece,
Australia.
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 = rep(c(1, 0),c(1, 1)))),
par.strip.text = list(cex = 1)))
