[R-sig-eco] Question about simprof

Dear R users, I am trying to conduct a simprof analysis to determine if groups of objects form statistically significant clusters. The variables that I am using are a mixture of categorical, ordered, and numerical. I am therefore using Gower's distance for this analysis. Below is the code with my

Re: [R-sig-eco] Heat Map for species - code from Numerical Ecology with R

Valarie, I too ran across this problem. vegmite operates on data with a single digit such as Braun-Blanquet cover estimates. Thus vegemite command will not work on data such as environmental data or biomass data unless you convert it to a single digit, causing you to loose a lot of information. So
