cca.phyloseq: Constrained Correspondence Analysis and Redundancy Analysis.
Description
This is the internal function that simplifies getting
phyloseq data into the constrained ordination functions,
cca and rda.
Unlike capscale.phyloseq, the
formula argument to these methods is optional, and
results in an unconstrained ordination.
Arguments
physeq
(Required). Phylogenetic sequencing data
(phyloseq-class). The data on which you
want to perform the ordination.
formula
(Optional). A formula,
specifying the contraining variable(s) format, with
variable names corresponding to sample_data
(RHS) from within physeq.
method
(Optional). A single
character string, specifying "RDA"
or "CCA". Default is "CCA".
...
(Optional). Additional named arguments passed
to capscale.
