I have a bunch of tables in a Microsoft Access database. An updated database
is sent to me every week containing a new table. I know that is inefficient
and weird but welcome to my life. I want to read the tables whose names are
something such as "040207" but not the ones that have alphanumeric names
such as "everyone". Using RODBC I am easily able to create a character
vector of the names of the tables. Is there a function that can
differentiate values consisting only of digits (numerics) as opposed to ones
that contain letters (and perhaps digts as well)? I am sure there is. What
is it and where should I have found it?
