Subject: [R-sig-eco] Minimum Number of Observations for pcaCoDa?
The compositional data sets have few observations: 4 to 7 rows each, but
there are 5 parts (columns) for each row.
I tried to use the robCompositions function pcaCoDa(). There was an error
and warning generated:
( winters.biplot <- pcaCoDa(winters.coda) )
Error in princomp.default(xilr, covm
