[R] SQL Primer for R

[ivo welch]

Sorry, chaps.  I need one more:

> dbDisconnect(con.in)
Error in sqliteCloseConnection(conn, ...) :
  RS-DBI driver: (close the pending result sets before closing this connection)
>

I am pretty sure I have fetched everything there is to be fetched.  I
am not sure what I need to do to say goodbye (or to find out what is
still pending).  ?dbDisconnect doesn't tell me.  PS: the documentation
for dbConnect should probably add "dbDisconnect" to its 'See also'
section.

regards,

/iaw

Really irrelevant PS: the "by" function could keep the number of
observations that go into each category.  I know it can be computed
separately, which is what I am doing now.
