Species scores are missing in dbrda, but this function can be used to add the species scores item to a dbrda() result object similarly as in other constrained ordination methods. This version is the one I suggested in https://stackoverflow.com/questions/46531969 and is still preliminary and incomplete (and undocumented and non-exported)
Together with previous commits in this branch, this implements the functions outlined in github issue #254 for adding species scores to ordination results. Still undocumented and non-exported.
This should be cherry-picked to the master even if this branch is not merged. This commit makes no reference to sppscores() development in this branch.

This PR is a response to issue #254. It adds a replacement function
sppscores<-to add species scores if they are missing, or replace species scores if wanted. With the current implementation, the usage will beRemoving
<-fromsppscores<-would change the usage toThe function is implemented for
dbrda(which never has species scores) and forcapscale&metaMDSwhich usually have species scores, but they may be missing or unsatisfactory.The PR is also more explicit on missing species scores. Moreover, information on species scores in db-RDA (
capscale,dbrda) is saved with the ordination object and displayed inprint.cca().
