ggshadow: Create faceted shadow plots

In Brattle/BrattleExtras: Functions and other objects for Brattle projects

Description

These functions create faceted shadow plots (all observations are shown in every facet greyed out with the facet's observations shown on top).

Usage

ggshadow_histogram(data, mapping = aes(), facet_var,
  nrow = NULL, ncol = NULL, bg_fill = "grey", bg_alpha = 0.5, ...)

ggshadow_point(data, mapping = aes(), facet_var,
  nrow = NULL, ncol = NULL, bg_color = "grey", bg_alpha = 0.5, ...)

ggshadow_line(data, mapping = aes(), facet_var,
  nrow = NULL, ncol = NULL, bg_color = "grey", bg_alpha = 0.5, ...)

Arguments

data	Data frame
mapping	Aesthetic mapping as in ggplot
facet_var	Character string of name of facet variable
nrow	Number of rows for faceted plot
ncol	Number of columns for faceted plot
bg_color	Color of background points/lines
bg_fill	Color (fill) of background bars
bg_alpha	Alpha value for background points/lines/bars
...	Arguments passed to plotted geom

ggplot, geom_histogram, geom_point, geom_line facet_wrap from the ggplot package. The gghighlight package provides related functions with somewhat different functionality.

Examples

ggshadow_histogram(diamonds, aes(carat), "cut")

### Reduce opacity due to overplotting;
### 'alpha' refers to facet points, 'bg_alpha' to shadows
ggshadow_point(diamonds, aes(carat, price), "cut",
  alpha = 0.2, bg_alpha = 0.1)
