Hi,
When you call plot() it will draw to the default device - in your case
the pdf() device. When the default device results in a file, R selects
a filename for you unless you tell it otherwise. You can specify the
filename by explicitly calling pdf() first.
pdf("var_plot.pdf")
plot(res.pca, choix="var", axes=c(1,2))
dev.off()
pdf("ind_plot.pdf")
plot(res.pca, choix="ind", axes=c(1,2))
dev.off()
See ?device for a listing of available devices.
