bars: Create Bar Charts

In pkollenda/pkgraph: Fancy Graphs with GGPlot

Description

Create a bar chart based on ggplot.

Usage

bars(data, count, group, highlight_variable = NA,
  ordered = "alphabetically", first_group = NA, flipped = TRUE,
  labelled = FALSE, show_percent = NA, label_nudge_y = -0.02 *
  max(select(data, {     {         count     } })), label_nudge_x = 0,
  label_size = 3, label_color = "white", label_hjust = "right",
  axis.title.x = element_blank(), axis.title.y = element_blank(),
  title = element_blank(), legend.position = "none", fontsize = 16)

Arguments

data	A data frame.
count	The variable that contains the number of observations per group.
group	The groups that are displayed as separate bars.
highlight_variable	Default NA, indicate variable that is TRUE only for the highlighted group.
ordered	Default alphabetically, alternative is count, then ordered in descending order.
first_group	Default NA, indicate a group which should be displayed first (left or top).
