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

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
http://webhelp.esri.com/arcgisdesktop/9.3/pdf/Whats_New_In_ArcGIS_93.pdf?
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.
