[R-SIG-Mac] Preparing mySQL queries for R and SNA

[Byron Ellis]

You can talk to MySQL directly from R (using the RMySQL and DBI
packages) so there's no need to create an intermediate file. My SOP is
to query the database wth dbGetQuery and immediately drop the results
into an Rda file (just in case).
