Dear All,

I hope this is a good place to post this. I'm working through the book 
"Applied Spatial Data Analysis with R" and on pg 59 the following code 
results in an error

 > data(meuse.riv)
 > meuse.lst <- list(Polygons(list(Polygon(meuse.riv))),"meuse.riv")
Error in Polygons(list(Polygon(meuse.riv))) : Single ID required

 > sessionInfo()
