Automagically calculate a point size for ggplot2-based scatter plots

It happens to look good

AutoPointSize(data, raster = NULL)

Arguments

data	A data frame being passed to ggplot2
raster	If TRUE, point size is set to 1

Value

The "optimal" point size for visualizing these data

Examples

df <- data.frame(x = rnorm(n = 10000), y = runif(n = 10000))
AutoPointSize(data = df)
#> [1] 0.1583
