There are jpeg(), png() and bitmap() devices and the dev2bitmap() function
under Unix versions of R, although they all require additional software at
the time R is built or is run.  The simplest way usually is to re-plot the
graph after opening a jpeg (etc) device, then call dev.off().

Call install.packages correctly with two arguments: see its help page.
install.packages("RMySQL", .Library) is probably what you wanted.
