[R-sig-Geo] Impact of ArcGIS 8.3 beta's new spatial statistical functions in its Spatial Analyst Extension

[Paul Hiemstra]

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
