Extract Last Two Numeric Parts From Character Vector

Usage

extractLast2numericParts(x, silent = FALSE, debug = FALSE, callFrom = NULL)

Arguments

x	main character input
silent	(logical) suppress messages
debug	(logical) additional messages for debugging
callFrom	(character) allow easier tracking of messages produced
