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

[Spencer Graves]

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
