What are you trying to do? I've done a few things with GIS point data in R, but it was a fairly simple data structure.

Thanks Kelly for your comment. I am going to prepare maps of fishing grounds, and may be spawning grounds and later I am going to investigate the environmental parameters, such as SST and bathymetry, which may be related to fish distribution.

I send you a link where you can download a tool to work with GLMs from ARCGIS. Use the R program as a plataform, does not seem too complicated and can be very useful. http://mgel.env.duke.edu/mget/download/

from GIS data can perform spatial analysis. There are several library in R. In particular sp library that allows you to import and analyze spatial coordinates. Then we can perform analyzes and maps that you want.

See:

I recommend reading this book:

Applied Spatial Data Analysis with R (Bivand et al, 2008)

Thank you so much Nicolas and Alian for your contributions.

Dr Nicolas, this should be very helpful to work in R from ArcGIS.
