Dear Martin, The plot you refer to is a scree plot.
One option (there are many) is to have a look at the nFactors package. Despite its package description, it includes the function plotnScree. You will find it helpful to search google for "scree plot R" and/or use rseek.org as there are many possibilities. Good luck.
