R help - Jan 2010 - BIOMOD: the format of background data

Dear,

I am a newbie to R.

I am trying BIOMOD to simulate species distributions with presence-only
data.

As the presence-only data consist of three columns, presence, longitude,
latitude,
please kindly share how to prepare the background data (maybe using ArcGIS
?)


Thank you

Elaine
