  maxcat = 50,
  order_bar = TRUE,
  binary_as_factor = TRUE,
  title = NULL,
  ggtheme = theme_gray(),
  theme_config = list(),
  nrow = 3L,
  ncol = 3L,
  parallel = FALSE
)

Arguments

data	input data
with	name of continuous feature to be summed. Default is NULL, i.e., frequency.
by	discrete feature name to be broken down by.
by_position	position argument in geom_bar if by is supplied. Default is "fill".
maxcat	maximum categories allowed for each feature. Default is 50.

parallel	enable parallel? Default is FALSE.

Details

If a discrete feature contains more categories than maxcat specifies, it will not be passed to the plotting function.

Value

invisibly return the named list of ggplot objects

Examples

# Plot bar charts for diamonds dataset
library(ggplot2)
plot_bar(diamonds)
plot_bar(diamonds, maxcat = 5)

# Plot bar charts with `price`
plot_bar(diamonds, with = "price")

# Plot bar charts by `cut`
plot_bar(diamonds, by = "cut")
plot_bar(diamonds, by = "cut", by_position = "dodge")
