gg_outlier_bin: Create a Histogram with Outlier Bins

In EdwinTh/thatssorandom: Contains functions posted on my blog

Description

Make a ggplot with 'geom_histogram' that contains outlier bins. Bins can be created for both floor and ceiling outliers. Code is experimental so expect some deviations from normal plotting, like messed-up grid lines.

Usage

gg_outlier_bin(x, var_name, cut_off_floor, cut_off_ceiling, col = "black",
  fill = "cornflowerblue", fill_outlier_bins = "forestgreen",
  binwidth = NULL)

Arguments

x	a dataframe.
var_name	the name of the variable to visualize.
cut_off_floor	the floor of the histogram, all values below it will be put in the same bin. If 'NA“ no floor bin is created.
cut_off_ceiling	the ceiling of the histogram, all values above it will be put in the same bin. If 'NA“ no ceiling bin is created.
col	the color of the histogram.
fill	the fill of the regular histogram bins.
fill_outlier_bins	the fill of the outlier bins, make them a separate color to stress there different nature.
binwidth	the binwidth of the histogram.
