The OP may be looking for recordPlot/replayPlot.
We were not told the OS (x11 exists even on Windows). The standard
screen devices on Windows (windows() ) and Mac OS X (quartz()) have plot
histories that can be used to flick between plots. And 'flick' is the
operative word here: it is quick and under mouse/PgUp/PgDn control.
AFAIR Rstudio has copied the idea.
With as many as 18 plots, I would be looking for more effective ways to
browse them, and probably produce PNGs to view in an image browser or a
multi-page PDF to browse in a viewer which showed thumbnails.
