Hi,
thank you for the reply.
Do you need this to be a file? Could it be a pre-parsed R object
instead?
Yes, and that can go into an .RData file.

I need to provide an external data/file in the R package. This has come as
a request from F1000 journal editors.
One way to solve this could be to write a script that imports the file
from inst/extdata using the facilities provided by your package and put
it in a file under data/, then document the resulting object.
What do you call this step? How do I do this?
I thought to loading the file as lazyload, .onload package something?
Best,

My understanding is that data() is for R-level objects, and so is
help(), most likely.

from inst/extdata using the facilities provided by your package and put

that if you build your package with --no-resave-data, it will remain an
R script that will be run during the data() call. (By default, your R
script will be run during R CMD build and its output will be packaged
into a gzip-compressed RData file.)
This might go against the guidance at
<https://cran.r-project.org/doc/manuals/R-exts.html#Data-in-packages>,
which says:
R code should be if possible “self-sufficient” and not make use of
extra functionality provided by the package, so that the data file
can also be used without having to load the package or its namespace
