Hi Barry,
Thanks for the response, your suggestion was going to be my 'work
around'... perhaps I took the second paragraph of section 1.1.5 of
R-exts.pdf the wrong way.
I'd be interested in knowing why there is a difference between the
data in a source package (.rda files) and windows binary package (.R
files) if anyone can tell me.
We have little idea what you did. Apparently you feel you are exempted
from the request in the posting guide for a reproducible example.
At a wild guess, you did not understand the point of R CMD build
--no-resave-data and did not want your data resaved as a .rda file (the
documented default). But there is no mention of running 'R CMD build' here.

Hi List,
I am building a package for a client to help them create and perform
analyses against netcdf files which contain 'a temporal stack' of
grids.
For my examples and test cases, I create an example dataset in code
(as this is a lot more space efficient than providing raw data). The
code creates a netcdf file in tempdir() and an object of class 'ncdf'
in the global namespace. I have placed the code in a .R file in the
data directory of my package and 'load' it with a call to data().
Why not just put the function that generates the data file into the
usual place (/R/ folder) and document it so that the user knows to run
'sampledata=makeSampleNCDF()' before doing things that need it?
Trying to put executable code into the data folder does seem a bit perverse!
Actually, it seems to be *interpretable* R code in a .R file.
The help file for data() says:
Details:
Currently, four formats of data files are supported:
1. files ending ‘.R’ or ‘.r’ are ‘source()’d in, with the R
working directory changed temporarily to the directory
containing the respective file. (‘data’ ensures that the
‘utils’ package is attached, in case it had been run _via_
‘utils::data’.)
...
and (in so far as we can tell without the requested example) that was
the 'format' intended to be used.
Barry
