[R] R Mysql Not reading all table names

[MacQueen, Don]

You could try
  dbListTables()
and do the subsetting afterwards.

Also try
  dbGetQuery()
instead of dbSendQuery()

(There's no obvious reason that I can see to use dbSendQuery() followed by
fetch. It would be interesting if the two ways return different lists of
tables.)
