Hi Dr. Oksanen! Its very gracious of you to respond. On another important note, this is the citation suggested for the vegan package:
Oksanen J, Blanchet FG, Kindt R, Legendre P, Minchin PR, O'Hara RB, Simpson GL, Solymos P, Stevens MHH, Wagner H. (2015) vegan: Community Ecology Package. R package version 2.2-1. http://CRAN.R-project.org/package=vegan Is this the most appropriate for our purposes (using Adonis and capscale in Vegan)?

However, in addition to variables in the data frame given in data=, you can mix variables in the work environment in your formula. If you think you need to have several data frames for the data= argument, please consider cbind(). cheers, Jari Oksanen _______________________________________________ R-sig-ecology mailing list R-sig-ecology@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-ecology
