Re: [R] 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
