Hi All R guru's,
A couple of simple questions which I cannot find answers to in "an
introduction to R" or in the reference manuals.
I am running R on Win95, and have plotted up quite a nice box and
whisker plot:
char<-read.table("n:/reddinm/grifpr~1/survey/char.txt")
attach(char)
boxplot(Al,Fe,OC,pH, range=0,xaxis=FALSE,
ylab="Proportion of Unirigated Soil
Characteristic",xlab="Characteristic")
nom2<-c("Al","Fe","OC","pH")
axis(1,1:4,nom2)
abline(h=1,lty=2)
The problems are these, how do I change the line width (lines are
all too light). I have attempted putting lwd=2 or something higher inside
the boxplot statement....
which it swallows without any complaints...it just doesn't seem to
change anything, either on the screen or when printed out.
Second problem, I find that the text quality when I export to a PNG
file is pretty bad...not good enough for publication.
I thought that I might be able to get HErshey fonts to improve
this...but can't get them to work.
Final question: I cannot get R to swallow the addition of
a font.lab(xxx,xxx) statement in the boxplot function......how do I
get it to use Sans Serif, and produce high quality output? How do I use the
font.lab command and the related commands.
Thanks for your help. It looks like a nice package from what I have
seen so far, so I'm keen to learn to
use it.

Hershey fonts won't improve it and will probably make it worse, as at least the standard TrueType fonts are designed to be rasterized, unlike vector Hershey fonts. Text quality will be particularly bad unless the PNG plot is printed at a small exact multiple of the design size (in pixels). Don't think in terms of PNG for publication (except Web publication). Use PostScript or (on Windows only) Windows MetaFiles as these are vector/font description formats. You can create or export to Windows metafiles directly, or via the clipboard. [...] -- Brian D.

Thanks for your replies Brian and Uwe,
I won't be trying to use PNG's for my purposes then.
To change the line widths the make the diagram darker and more conducive to
publication, I have to go back to the source code for bxp(.), then?
There are no parameters from within R that can change this?
Thanks,

I've worked out how to do this,
So no need to reply to the previous query.
I have used the Par(lwd=2) command, which increases line thickness.
......Now I simply have to find how to change to a sans serif font, and I
will be OK.
Thanks,
