[R] Cannot load vegan and vcd, "object vI not found"

[Camilo Bernardo Garcia Ramirez]

Hi again: First at all, thanks for your answer. My problem is still there.
Here the session. I did remove and (re)install vegan and then called for
update but no effect in the error. I included the sessionInfo() at the end.
