factanal and plotting?
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. Best wishes, Mark

Hi there! To make a good choice for the estimation of the number of usefull factors. And I'd like to plot a graph like: http://de.wikipedia.org/wiki/Bild:Parallelanalyse.jpg where I don't need the green line (random values). But with str(factanal(data, factors=10)) I cannot figure out where I can find the values for plotting. Can you please help me in this question?
