bug in plot.envfit

[XavierTB]

Hi, I came across a possible bug in vegan 2.5-4 with plot.envfit
When I plot an envfit object with the at=c(x,y) argument, the vectors' origin is displaced by x,y, but the labels are displaced by 2x,2Y, as in the following instance:

generated with:

plot(env)
plot(env,at=c(1,-2))

I had a look at plot.envfit, I think the offending line is:

 vtext <- sweep(vtext, 2, at, "+")

because vtext is already at the new location from the previous ordiArrowtextXY command

Thanks for reporting this. It is now fixed following your suggestion (plus some fine tuning).
