RMySQL Installation Challenges

I loaded RMySQL package so I could connect R to MySQL.  I used the install feature within R Studio.  The package installed without errors, but when I tried to use the dbConnect function I would get this message Error: could not find function "dbConnect".  I finally tried 'library(RMySQL)' and that did the trick.  Also had to run 'library(DBI)'.  DBI was installed with RMySQL as a dependency.
