Impact of ArcGIS 8.3 beta's new spatial statistical functions in its Spatial Analyst Extension
Paul, Not to mention the huge cost of ESRI products and the fact that they run only on the MS-Windows platform. R also integrates well with GRASS GIS. Personally, I can not see any compelling reasons to go the ESRI route vs R/GRASS? I feel a great debt of gratitude to the selfless developers of R & GRASS!

Dear Hisaji, I think that the choice of people for R is not only based on the fact that a certain method is only available in R. R is much more flexible in working with data, allows scripting, allows you to see exactly how a method works, allows you to extend or develop methods and if you write in script files it also provides a record of what you have done. Apart from spatial analysis, R also provides a very wide range of "normal" statistical methods that are not available in ArcGIS (linear regression and such). So I don't think a lot of people will forsake R once a few more methods become available in ArcGIS. regards, Paul Hisaji ONO wrote:
Hi. What do you think about ArcGIS 8.3's new statistical functions(Calculation of spatial or network, GWR, Global/Local Moran, Gi etc.) in its Spatial Analyst Extension described in
Current R's spdep's and spgwr's and others' end users will loose interests of them and go to use ESRI's apart from R's? And will decrease activities of developments of (geo)spatial data analysis tools in R? Regards.
