I am new(ish) to R and Biomod and am modelling the response of a suite of species to a number of environmental variables.
I have a DEM at 3 differing resolutions containing 2.6 million, 23 million, and 220 million grid cells. When preparing data for import to R for modelling species distributions in BIOMOD, do I need to include the lat/longs and values of each of my environmental variables for every grid cell of the DEM??, and then specify presence/absence for my species, or just the values in the grid cells where I have species presence???
Also, what is the best format for my data?? At the moment, I am importing my data to .txt format as .xlsx can only cope with 1.04 million rows.
Thanks in advance
