## Hmisc options for pdflatex
## graphics files are .pdf

## This file is close to tutorial in that it displays many pdf files
## each illustating different values of the control arguments.

## These are the LaTeX options I use

## latex draws the panels top left to top right then down,
## eventually getting to bottom right.
##
## trellis, by default with as.table=FALSE, stats at bottom left, then
## writes rows left to right, eventually at top right.
## latex.trellis reproduces the appearance of the displayed trellis plot.
