How to weight smoothing by arbitrary factor in ggplot2?

ggplot2, r

Solution

As Ben noted above, if you change the first line to

ggplot(top10,aes(x=FT,y=PPS,size=FGA,color=PPS,weight=FGA))

it works.

Here's a corrected version:

Problem

The following is a relevant example. I'm looking at shot efficiency as a function of distance for NBA players. I want to weight the smoothing by the volume of shots taken at each distance (i.e. the size of the bubbles). Is there a way to do this? The command to generate this plot was: ``` ggplot(top10,aes(x=FT,y=PPS,size=FGA,color=PPS)) +scale_x_continuous(limits = c(0, 30)) +scale_y_continuous(limits = c(0, 2.2))+geom_point() +facet_grid(NAME~.,space="free") +stat_smooth(color="darkblue",size=2) ```
