[R] Allarme generato mediante Panda GateDefender Performa.

[Tom Backer Johnsen]

I have been looking at the documentation and the output from the 
functions princomp() and factanal(), and found them somewhat difficult 
to understand.  This is probably due to differences in respect to what 
I am used to with respect to terminology (my field is psychology). 
Are there some additional texts which might help?

Sincerely,

Tom
