Dear Peter,
Thanks for your reply, and pointing out my mistake of misspelling in
'Permanganate' variable.
However, it couldn't be detected because the same code, with misspelled
variable at factor declaration level, ran successful ly till I upgraded to
R-4.0.0 and later to R-0.1.
I am sure the bug pointed out by you would taken care of soon. Thanks again.
With best regards,
Dr. A.K. Singh
