Dear Troels
Perhaps I misunderstand what you are trying to do but would it be
possible to put each x and y into a list or a dataframe with different
names and then modify your usgae to pull them from there? Then there
would be no danger of users getting the wrong x and y

Dear friends - I have a package under creation making heavy calculations on
chemical/clinical data and I plan to include as "examples" the use of some
literature data used in my papers. To illustrate what then occurs, I made
two RData files consisting only of x and y with different values for x and y
like
X <- 100
Y <- 1000
save(x,y,file="first.RData")
and then a new x and y in "second" with x <- 45 and y <- 32
When I put these in a "data" directory of a new package without further ado
in RStudio
Ctrl-shift-L
Ctrl-shift-B
.there is a warning
* installing *source* package 'try' ...
** R
** data
*** moving datasets to lazyload DB
warning: objects 'x', 'y' are created by more than one data call
** byte-compile and prepare package for lazy loading
** help
converting help for package 'try'
*** installing help indices

Now, when I clear the workspace:
ls()
character(0)
devtools::load_all(".")
Loading try
Restarting R session...
library(try)
ls()
character(0)
x #-- so even if workspace Is empty x is still kept
[1] 45
data(first) # and "first" is not seen
x
[1] 45
x is still present - and y
I have been reading and searching in "Writing R extensions" but so far
didn't find the clue.
Seemingly it is the file with the last name that is assessed - when I rename
first.RData to "xfile.RData" we get 100 and 1000.
Now and then when running ctrl-shift-L and - B we see
Attaches package: 'try'
The following objects are masked _by_ '.GlobalEnv':
x, y
Sorry for these problems -
