[R-sig-eco] About biplot analysis in ADE4GUI

[mujeeb rahman]

I am new to R, but learned to use ADE4GUI, and run PCA analysis. I donot
know how to create a BIPLOT using Classes.
I used soil fauna count data -abundance- the details are as follows
number of rows 60 (from 15 habitats x 4 replicates)
number of columns (17) ie, 17 soil faunal group
the scatter file is attached for reference.

*in the example file explained in Interactive Multivariate Data Analysis in R
with the ade4 and ade4TkGUI Packages by usinf file meaudret, they created
the biplot. I tried the procedure, but unsuccessful.*

*Awaiting for your suggestions*
