[Spencer Graves]

Hi, Ivan and Uwe:


	  Thanks for your suggestions, but I've so far been unable to get them 
to work.  see below.

	  In RStudio 2022.12.0+353 (the current version),


tools::showNonASCIIfile('https://raw.githubusercontent.com/JamesRamsay5/fda/master/NAMESPACE')


returned "char(0)".  'readLines' and 'writeLines' as Uwe suggested 
failed to fix it for me.


	  The first problem I noticed with this was that RStudio could not read 
the NAMESPACE file.  When I tried, it said, "File is binary rather than 
text so cannot be opened by the source editor."  I changed something 
using a different editor and did "git commit" and "git push", and got 
the error on GitHub that I reported above.  I copied the file elsewhere, 
deleted it locally and from GitHub, then recreated it in LibreOffice by 
manually typing the first and last lines then copying the rest from a 
copy I had saved elsewhere.  The RStudio would open the file, but I 
still get the same error message as above from both "R CMD build fda" 
locally and from GitHub Action at:
