Further to Joris' email, the help page of data() is very informative.
If the reason for wishing to combine the datasets together is so that they can be made available in a single command,
an option might be to create an R source file which loads all datasets, thus giving this option without withdrawing the possibility for loading the individual datasets.

in the data() function you have to use the name of the rda file, not the
name of the dataset you need.
So say you have the datasets validity and data2 in a file called
alldata.rda, you need to do:
and that will make both validity and data2 available to the user.
imho it only makes sense to combine data in one .rda file when they're also
related (for example an dataset with species and the similarity matrix for
Hope this helps
