Document related datasets in one file

[hadley]

e.g.

#' World country polygons from Natural Earth.
#' 
#' @name countries
NULL

#' @format A \code{SpatialPolygonsDataFrame} with 177 elements
#' @source \url{http//www.naturalearthdata.com/download/}
#' @rdname coutries
"countries110"

Note that roxygen will automatically supply:

#' @docType data
#' @keywords dataset
#' @usage data(countries50)

so you can drop them

Thanks, done, although is it possible to get e.g. ?countries110 to work ? I tried with @aliases but doesn't seem to

[hadley]

Yes. You shouldn't need to do anything extra (but you might need to build and reload the package)

[andysouth]

Thanks, that worked.
