The precedence of partial name matching over the ellipses

[ecoRoland]

This leads to trouble when trying to pass n to stat_density2d in geom_density2d.

set.seed(42)
df <- data.frame(x=runif(100),y=runif(100))
library(ggplot2)
ggplot(df,aes(x,y)) + geom_density2d(stat='density2d', n = 100) 
#Error: is.logical(na.rm) is not TRUE

ggplot(df,aes(x,y)) + geom_density2d(stat='density2d', na.rm = TRUE, n = 100) 
#works
