R devel - Apr 2002 - ylim in biplot does not seem to work (PR#1498)

Hi all,

I've searched the known bugs and hopefully I did not oversee this one...

When I have done a normal
zz<-princomp(na.omit(raw.data))

and I then draw a biplot with
biplot(zz,cex=c(.1,.7),col=c(5,1),choice=c(1,2),xlim=c(-2,2),ylim=c(-5,2))

the x axis gets set properly, but the y axis remains unchanged.

Cheers,
hinrich   d8-)

You are using biplot.princomp here.

It works for me:

# example(biplot.princomp)
data(USArrests)
biplot(princomp(USArrests))
biplot(princomp(USArrests), ylim=c(-0.5, 0.5))

Note that there are two y axes, and both are changed.

Please read the section in the FAQ about supplying a reproducible example
if you think you have found a bug.

BTW, setting the axes on a princomp biplot seems unlikely to be
statistically sound to me.
