[R] [R studio] Plotting of line chart for each columns at 1 page

[Bert Gunter]

You need to do some studying! ggplot is built on the grid graphics system,
which is separate from the base graphics system. The par() function is part
of the *base* graphics system and so ignored by ggplot.

Others may offer you solutions using the "faceting" functionality of
ggplot. But you really should reading up on this on your own. There are
many good tutorials on ggplot2 that are available on the web.
