Parameter to set the position of the legend. Can be given in form of a string
(bottom|top)(right|left) for base graphics and bottom|top|left|right
for ggplot2. It can be a two-elements vector, which specifies the relative position on
the x and y axis respectively, or alternatively it can be in form of a logical variable,
with TRUE indicating to use the first standard and FALSE to use the second
one. Default value is c(1,0.5), that is on the right inside the plot area.
graph
A string used to select the graphical engine to use for plotting. Should
(partial-)match the two options "base" or "ggplot2". Default value is
"base".
Value
mceplot
A ggplot object containing the plot. Returned only if graph="ggplot2".
