[R-sig-Geo] tolerance in points2grid()

[Agustin Lobo]

Hi!

I do
points2grid(tmetad1)

and get:
suggested tolerance minimum: 0.000856898
Error in points2grid(tmetad1) :
  dimension 2 : coordinate intervals are not constant

then just try:
tmetadg <- points2grid(tmetad1,tolerance=0.000856898)

and works fine. But this is very inconvenient unless the task is being carried
interactively. Is there a way of actually geting the value of the
suggested tolerance into
a variable?
Also, why not having the option:

tmetadg <- points2grid(tmetad1,tolerance="suggested")

Thanks
