Figure 8-36. Left: polar plot with theta representing x values from 0 to 12; right: the gap is filled in
by adding a dummy data point for month 0
NOTE
Notice the use of the
%+%
operator. When you add a data frame to a
ggplot
object with
%+%
, it replaces
the default data frame in the
ggplot
object. In this case, it changed the default data frame for
p
from
md
to
mdnew
.
