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

[Sarah Goslee]

Hi,

You misunderstood the suggestion, which was to run update.packages()
to update all packages, not just vegan (which doesn't need updated
because you just reinstalled it).
To make your own life easier, I'd run it as:

update.packages(ask=FALSE, checkBuilt = TRUE)

You could also try reinstalling the packages that vegan requires,
which seems to be where the error actually is. (lattice, perhaps, but
I'd reinstall
