Runnig the examples from ?betadisper and adding a pch statement gives:
> plot(mod, pch=2)
Error in plot.xy(xy.coords(x, y), type = type, ...) :
formal argument "pch" matched by multiple actual arguments
> traceback()
5: plot.xy(xy.coords(x, y), type = type, ...)
4: points.default(g$centroids, pch = 16, cex = 1, col = "red", ...)
3: points(g$centroids, pch = 16, cex = 1, col = "red", ...)
2: plot.betadisper(mod, pch = 2)
1: plot(mod, pch = 2)
This shows that the author hardcoded the pch in the code, hence you can
only change it by changing the code - or send a feature request to the
vegan maintainer (ideally including a patch, CCing).

Hello!
After performing an analysis with betadisper, package vegan I would like
to plot the results - so far, so good. But I would also like to "tune" a
little bit the plotting characters, as '+' and 'x' are a little to
similar...
My (boiled down) code:
[See session info at the bottom of the mail, vegan is vegan_2.0-3]
mod <- betadisper(mydata, mygroups, type='median')
syms <- c(rep(1:4, each = 16))
modplot <- plot(mod, axes = c(1,2), main='', pch=syms)
I get the error message (roughly translated from german):
"formal argument 'pch' fits to more given arguments"
[formales Argument "pch" passt zu mehreren gegebenen Argumenten]
What do I have to change?
Thank you in advance!
