The interpreter parses atoms composed only of [digits, "-", "."] ,
i.e. "numeric", differently than it parses atoms with leading
[alphas]. Please study the introductory material more thoroughly where
this is all explained and illustrated. And do provide minimal
reproducible examples. That might be especially important here , since
failing to include the quotes could be very prone to error if the
underlying object is a factor variable.
