For base graphics, 'thigmophobe.lables' in the plotrix package also works to
avoid label overlap.

The xlabs= (rows) and ylabs= (columns) arguments handle the labels, but they do
not recycle so you need to specify values for each row and each column:

I am trying to understand how the biplot.prcomp is constructed so I can

The prcomp model I have ran has cor=TRUE and scale=TRUE

Probably so that the end of the arrow does not overplot the labels.

Hi, You can make a biplot on Your own, it is not so hard. And in this
case You can change parameters for every low level function as You
wish.
PC <- prcomp (iris[,1:4])
lambda <- PC$sdev * sqrt(nrow(PC$x))
plot (t(t(PC$x)/lambda),pch=16,col=as.numeric(iris[,5]))
par (new=T)
Rot <- t(t(PC$rotation)
Taking the example from ?biplot.princomp with reproducible code (hint,
hint):
biplot(princomp(USArrests))
biplot(princomp(USArrests), col=c(2,3), cex=c(1/2, 2))
clearly changes the color and font size on my system. For changing the
"point symbols" (which are text by default), try setting xlabs a
qplot(V1, V2, data=f, colour=site) + geom_path()
works thanks for the help

How exactly do you want to connect them? One approach is:
qplot(V1, V2, data=f, colour=date) + geom_path()
# or maybe

That's not how biplot.defa
Also check the asp= parameter in plot.default and plot.window; this sets
the aspect ratio so that 1 unit in x is the same physicla length as 1
unit in y. I don;t know whether it is respeced by your particular
biplot, though.
