[R] A humble request

Sun Jul 3 13:24:52 CEST 2022

Muhammad Zubair Chishti:

	  What specifically have you tried?  What were the results?

	  Please "provide commented, minimal, self-contained, reproducible 
code", per "the posting guide 
http://www.R-project.org/posting-guide.html", as indicated in at the end 
of each email in this thread.

	  And don't overlook the suggestion I made:  Download the archived 
package.  Do NOT try to compile it. Instead source only the function you 
want, try to run it.  With luck, it will work.  If it doesn't, you will 
get a diagnostic that can help you take the next step.

	  Spencer
