[R-sig-Geo] Problem with tryf parameter at low number of occorrences

[agus]

Dear all,

I am trying to use the function "randomPoints" for modelling distribution
from a very low number of occorrences:

    Longitude  Latitude
161  144.6333 -18.11667
163  144.0000 -18.03333
164  144.5500 -18.21667
165  144.6167 -18.1166

I am using parameters as explained in the SDM in R pdf:

However, despite this workedd well for species with a greater number of
occurrences, this time it showed me the following error message:

"Error en randomPoints(AU.environment, n = 500, ext = ext, tryf = 100,  : 
  generated random points = 0.06 times requested number; Use a higher value
for tryf"

I tried values of tryf about100, but still got the same result. Anyone might
throw some light on this?

Thanks a lot!
Agus Camacho
