Look at this. Not sure if this is indeed what you want or if you
actually have to unproject them.

Dear R colleagues,
Does anyone know if it's possible to create a vector with
coordinate values extracted from a shape loaded with readShapePoly
command of "maptools" package?
For example, the following code loads the shapefile containing
Brazilian states division:
library(maptools)br<-readShapePoly("BR-map/3.shp")
What I need to do is create a vector which contains all lat and
lon values inside this shapefile...
Thanks in advance,
Thiago Veloso.
