geom_smooth_tern | R Documentation |
Aids the eye in seeing patterns in the presence of overplotting.
geom_smooth_tern
and stat_smooth_tern
are effectively aliases: they
both use the same arguments. Use geom_smooth_tern
unless you want to
display the results with a non-standard geom.

Number of points at which to evaluate smoother. |
