If you specifically need the plot to have a dimension measured in
pixels, then you need to use a bitmapped format such as png and specify
the output to be the size you require:
png(test.png, width = 300, height = 300, ...)
DoYourPlotHere()
dev.off()
Do this directly using the png() device,

Hi,
I plan to run amova in R from randomly generated subsets of my original dataset.
The structure of my data looks as below:
region - rep(c(east,west),each=8)
pop - c(rep(1:4,each=4))
ind - c(rep(1:4,4))
l.1 - c(1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0)
l.2 - sample(c(0,1),16,replace=T)

Actually, R does not accept NA. First, the action is from lm and not from
the R base, and second, NAs are in fact deleted and not accepted.
Function lm() has a na.action argument which is by default na.omit. You
could easily make na_and_inf.omit and use it. You could also use
subset=(w 0).
