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 [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
