What does it mean when one of my variables was not analyzed in my RDA analysis, and that it was classified as NAME: ALIAS, TYPE: CHARACTER, VALUE: PRECIPITATION ??
For some reason the redundancy analysis does not want to analyze my three variables together (environmental), if I modify one of them by some other variable (for example a physicochemical), if I do the complete analysis, and I do not understand why this is happening.
I don't think I've seen too many discussions of redundancy analysis on this forum, and so I don't think you can take for granted that most folks looking at your question will have the background knowledge to immediately recognize your issue and suggest a solution.
