I don't know if this is the exact purpose of this forum, but perhaps you could redirect me.
I have an OTU x sample table and a sample x environmental variables table. I'm looking for ways to see which OTUs (or taxa) are significantly linked to environmental variables.
Taking this a step further, when I do a network analysis (co-occurence) of my OTUs, I'd also like to see which environmental parameters are significantly associated or correlated with the observed clusters.
Anybody who could set me on my way? I'm basically doing my analysis in R, currently using phyloseq for the network analysis, but I'm stuck with the superimposing of the variables ...
