[R] Problem with uploading library

[Joshua Wiley]

Dear Gaja,

If "sp" and "maptools" are not already installed, you'll need to do
that.  It is often recommended that you update your existing packages
before installing new ones.  Once that is done (or if you have
already), then you just need to load the packages, and then R will be
able to find the readShapeSpatial() function (it is in the 'maptools'
package).  Something like this should get you going:

########################
update.packages()
install.packages(c("sp", "maptools"))
require(sp)
require(maptools)
?readShapeSpatial #documentation
towns <- readShapeSpatial("OB/OB.shp")
############################

Hope that helps,

Josh
