In the Gnesfa paper, when you explain the examples and compare the
eigenvalues of the 3 analysis, you mentioned a significance test for the
eigenvalues. For example, at the end of page 680: Indeed, the tests of the
first (γ1 = 1.61, P0.002) and of the last eigenvalue (γ6 = 0.53, P0.002)
were
I have another question (oops)!!
When you do the randomisation test for ENFA and plot the result (with
scatter() function), what's the meaning of the arrow value?
It is not possible to use the function scatter to plot the result of a
randomization test.
I do not understand your question

Hello,
I'm looking for interest in this functionality and eventually working
it into a package.
I don't actually use LAS data much, and only have one example file so
I'm hoping others who do or know others who would be interested can

Hummm, true, I got confused! Sorry!! I meant scatter.enfa.
What I don't understand is the length of the arrows. The grid is d=2,
different from the grid set with the biplot of marginality and
specialization (d=0.5). In that case, the length make senses to me, but I
don't understand it in the
Thanks Alex, I will eventually post this to a broader audience.
I've used liblas and lastools, but the aim here is for a pure R
implementation that is built directly from the LAS specification
without 3rd party tools.
The R code already works quite well to extract x/y/z/time/intensity,
it just
