As already requested, please don't cross-post. Send your message to either the ecology list or the main help list, but NOT both. > Please kindly advise manuals dealing with the object list (or dist). > In addition, I would like to show the beta diversity index in a map. > Please kindly advise any other R package in need. Every intro to R ever written talks about working with lists: they're a core class. You could try the one that came with your R installation and is on the main R website, or google for more options. Also note that in my original reply to the ecology list, I gave you a full working example. I can't answer your map question, because I don't have any idea what kind of spatial data you have to work with. GPS coordinates? Shapefiles? Raster? I can recommend the book Applied Spatial Data Analysis with R by Bivand, but I can't give concrete suggestions without a reproducible example.
