[R] Unexpected mfrow, layout behavior (pdf still has multiple pages)

2009-02-05 Thread Paul Johnston 
My goal is to create a graph with one column and three rows into a
single graphic. The mfrow, mfcol, and layout functions all have the
same effect: three graphs are produced in a single pdf file, having
one graph per page.  This is not what I want (I didn't want multiple
pages).  Just before I sent this post, I was able to generate the
desired output with split.screen.  Is this the expected behavior of
mfrow and layout?

Paul



My code is as follows (ToruosityPlot and DiameterPlot are essentially
identical to LDRPlot).

layout(matrix(1:3, ncol=1))
#par(mfrow=c(3,1))

pdf(results.pdf, width=4, height=3, pointsize=4, colormodel=cmyk,
onefile=TRUE)

TortuosityPlot(left, right)
DiameterPlot(left, right)
LDRPlot(left, right)

dev.off()

LDRPlot - function(left, right)
  {
plot(left$x, left$LDR, bty=n, ann=FALSE, xlim=c(-1500, 1000),
ylim=c(1.0, 1.5))
abline(v=0, col=gray(.90))
lines(left$x, left$LDR, col=green4, lty=solid)
points(left$x, left$LDR, bg=limegreen, pch=21)
lines(right$x, right$LDR, col=blue4, lty=dashed)
points(right$x, right$LDR, bg=blue, pch=21)
#title(main=LDR, xlab=Distance (um), ylab=LDR,
col.main=black, col.lab=gray(.4), cex.main=1.2, cex.lab=1.0,
font.main=4, font.lab=3)

If you call them before opening the device, then yes, they will not
affect that device, but presumably some other device...

You are correct, thank you. I added a new subsection 'Graphics
Devices' in http://wiki.r-project.org/rwiki/doku.php?id=tips:surprises:traps
to document this behavior.
