Thank you for your elaboration.  This issue is related to curl trusting a CA cert as its called by R.  
curl called from bash recognizes the system cert bundle for CA's, curl called from R does not.

may I know how to trust the system certificate bundle from within R?

Should not matter.  Use any command-line client (wget, curl, ...) or R's
download.file() to slurp down  http://$MYSERVER/src/contrib/PACKAGES to
inspect, compare, ... -- and that is an absolute path so the index does not
