Had looked into the vignette. No, it does not really help. spRbind() is only
mentioned in 2.1 Dissolving Polygons and not in 3.1 Combining
Positional Data.
Including an example where the non-unique Polygons ID slot values occurs in
section 3.1. and the way to fix it using spRbind() would be very
Looking at the code,
x = rbind(x1, x2, x3, makeUniqueIDs = TRUE)
ought to work, but I haven't tried.
You are right that neither ?rbind nor ?rbind.SpatialPolygons tells you

Racine and Rowlingsonâs pages are a nice ways of presenting information. Now
suppose we start with the simplest genus â points, which have 3 species:
matrix {base}
ppp {spatstat}
SpatialPoints {sp}
For an object of one of these classes a student would want to know how to:
1. construct
