Hi Dragos,
I dont know anything about fuzzy set ordination but I know you can
deal with your data set using NMS (nonmetric mulitdimensional
scaling) in the software program PRIMER6.

Hello,
I have a matrix with 180 plant species (variables, binary) and
270 rows (altitude waterbodies). There is also one categorical
variable (4 categories representing similar lakes groups, which
resulted from a prior analysis of the transposed matrix).
Is there any way to load plant species on those categories in
fuzzy-set-ordination analysis? Is there anyone here that has faced
this question before or could provide a hint? All my efforts so
far have lead to loading the lakes on the categories (fso in R);
but I want to load the plant species.
I would greatly appreciate your help.
