Sorry, my mistake. This works
data(meuse.riv)
meuse.lst <- list(Polygons(list(Polygon(meuse.riv)),"meuse.riv"))

Dear All,
Sorry, by mistake I replied to the last message, but this is unrelated.
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
