R help - Apr 2014 - figure margins too large

Dear R experts,


I tried to plot some figures in R using postscript(), but it always shows that
the fugures margin is too large. I don't know how to change it. The
following is my example:

>
postscript("All.eps",width=3.27,height=1.416,pointsize=12,family="Arial")
>par(mar=c(5.1,4.5,4.1,2.1));boxplot(All~Nameall,ylab= expression(Size~ (log
[10]~mm ^2)), boxwex=0.3, main="All
species",col=c("red","yellow","blue"),ylim=c(0,4.0))
>Error: plot.new() : figure margins too large

When I run the boxplot in R, it shows well, but once I run it in the postscript,
it fails. Can someone help me on it?
Note: my operational system is windows 7.


Many thanks in advance
Yichun

Hi Yichun,
It is probably because you are trying to set up a very small postscript 
device, and after the margins have been allocated, there is no room for 
the plot. Try doing the plot with a larger size (e.g. width=8, height=4) 
and see if you can scale it down afterward.

Given your pointsize, the margins take up all the plot.  So do one of

- increase the device size (recommended)
- reduce the pointsize
- reduce the margins (the par(mar=) setting), carefully

Also, you have not shown us the 'at a minimum' information asked for in 
the posting guide, but family = "Arial" is unknown in current R (3.1.0
RC has "ArialMT"), and that call will not produce an EPS file.
