effect_plot {baggr} | R Documentation |
This function plots values from effect_draw, the predictive distribution
(under default settings, posterior predictive),
for one or more baggr
objects.
effect_plot(..., transform = NULL)
... |
Object(s) of class baggr. If there is more than one, a comparison will be plotted and names of objects will be used as a plot legend (see examples). |
transform |
a transformation to apply to the result, should be an R function;
(this is commonly used when calling |
Under default settings in baggr posterior predictive is obtained. But
effect_plot
can also be used for prior predictive distributions when
setting ppd=T
in baggr. The two outputs work exactly the same, but
labels will change to indicate this difference.
A ggplot
object.
effect_draw documents the process of drawing values;
baggr_compare can be used as a shortcut for effect_plot
with argument
