Hi Erin, you need the CTV package in order to install a CRAN View. So
something like the following should work:
install.packages("ctv")
library("ctv")
install.view("Spatial")

Dear R Sig Geo People:
I'm trying to install the "Spatial" as found in Bivand et al. I'm in Windows
with R-2.14.0 on an XP machine.
Here is what I did:
> library(sp)
> install.views("Spatial")

Shapefiles, specifically dbf tables, do not support Date/Time fields -
well at least date & time in the same field. You must set your column as
Posix type or Character before export to ensure the values are written
as a text column in the dbf file.
Enjoy,
Alex

Tom,
Thanks for the information.
I guess there are different learning styles. I do not enjoy watching video
lectures so I don't inflict them on the students in my distance education
course that I am publicizing here
(http://www.itc.nl/personal/rossiter/teach/degeostats.html). I don't even watc
Hi David,
If this can be of any help, at GEOSTAT we started recording/broadcasting
all lectures (this was an excellent idea of Ralf Schäfer and his team at
