Monte Carlo test on ENFA results problem

Dear all,

I am doing an ENFA and MADIFA analysis and I have problems with the 
randtest.enfa command of the adehabitatHS package. It does not work even 
if the pc works for hours. I also used the command of the old adehabitat 
version but the problem is the same.

Do you know if there is an alternative command(s) that I can use to 
perfom a Monte Carlo test on ENFA results (I need to obtain the p-value)?

Another question is about the graphs of the MADIFA test that I have 
attached. Can anybody help me with the problem in the figure 
madifa284.jpg??? Any idea?
  I also attached the figure relative to the scatter plot of the same 
madifa results (scatter_mad284) where it seems that there are not problems.

Thanks in advance for any help,

Bye,

Michela
