You have to document each data object, but there can be multiple objects
in an .RData file.
So for foo.RData the call data(foo) could make several objects
available, each of which has to be docuemnted.
Not sure about Hadley's book, nor roxygen, nor RSTudio, as I'd do all
this in plain R.

Dear friends - I noticed in Hadley Wickham's comprehensive book on packages
under "exported data" that the .RData file in data directory is "containing
a single object (with the same name as the file)". However, in the "Writing
R extensions" 1.1.6 - when discussing images created by save there is no
statement I can see that the RData should only contain a single object? Is
that common knowledge?
I got a problem when adding the code below to an otherwise well working
datasets.R in R directory - wonder if it is connected to the above since
Baaeza.RData contains multiple objects.
#' routine for multiequilibrium problems

#' @description Data from Baeza-Baeza et al.

#' @format A worksheet.
#' \describe{
#' \item{Na}{Strong ions}
#' }
#'
#' @examples
#' data(Baeza)
#'
"Baeza"
And even though I have Baeza.RData in the /data directory ctrl-shift-B
stopped immediately with

Loading acidcharge
error: 'baeza' is not exported object from 'namespace:acidcharge'
run stopped
Exited with status 1
