Monte-Carlo test on a Statico analysis (in C).
Performs the series of Monte-Carlo coinertia tests of a Statico analysis (one for each couple of tables).
statico.krandtest(KTX, KTY, nrepet = 999, ...)
KTX |
an objet of class ktab containing the environmental data |
KTY |
an objet of class ktab containing the species data |
nrepet |
the number of permutations |
... |
further arguments passed to or from other methods |
krandtest, a list of randtest objects. See krandtest
IMPORTANT : KTX and KTY must have the same k-tables structure, the same number of columns, and the same column weights.
