Problem with read.shape in maptools

Hi,
I'd like to read a shapefile into a Map object. This is exactly what
read.shape{maptools} is suppoed to do, according to the documentation I
found in the link below.
Do search the archives properly; the second hit on googling "list:R-sig-geo read.shape" is relevant. Summarize to the list when you've resolved your problem. In addition, R is case specific, so an S3 Map object is not an S3 map object. Your previous mail refers to a function in the maps package, which does things that may be supported elsewhere. The only function that seems to convert SpatialPolygonsDataFrame to a list like the map class is fortify.SpatialPolygonsDataFrame() in ggplot2, but I don't know if this does what you need. To be honest, you havent't explained what you want to do with smooth.map that you cannot do with sp objects - please do read the available documentation before cross-posting (first post). Roger
However, this doesn't seem to work
library(maptools)x <- read.shape(system.file("shapes/sids.shp",
package="maptools")[1])Error: could not find function "read.shape"
I haven't found this function on the documentation from the latest
release of the package, so I assume is no longer supported. Is there
an alternative way of doing this?

Thanks,
