[R-pkg-devel] How to remove rJava from Ecfun when it's not called directly or indirectly

On Sat, 10 Oct 2020, Spencer Graves writes:

Hello, All:


	  "R CMD check Ecfun_0.2-4.tar.gz" fails under
Windows 10 with "Error: package or namespace load
failed for 'Ecfun': .onLoad failed in loadNamespace()
for 'rJava'".


	  However, I cannot find where Ecfun calls rJava.  This is in:


https://github.com/sbgraves237/Ecfun

	
	  I get nothing from "grep 'rJava'" in the
DESCRIPTION and NAMESPACE files plus in the man and R
subdirectories.  I ran tools:package_dependencies
recursively starting with Ecfun until I got all NULLs
and could not find rJava anywhere.


	  Thanks,
	  Spencer Graves

Hello Spencer

Just a wild guess: the CRAN version of your package
does not list 'xlsx'; but your GitHub version does.
Now, 'xlsx' depends on 'rJava'.  So perhaps start there?

As I said, only a wild guess; but maybe it helps.

Kind regards
