Create a bar plot from a data frame through ggplotly

Description

Create a bar plot from a data frame through ggplotly

Usage

make_barplot(
  dt,
  bars,
  value = NULL,
  break_bars_by = NULL,
  up_to_n_bars = 20,
  horizontal = FALSE,
  sort_by_value = horizontal,
  sort_decreasing = TRUE,
  ggtheme = "minimal",
  x_axis_label = NULL,
  y_axis_label = NULL,
  plot_palette = NULL,
  plot_palette_generator = "plasma",
  static = FALSE
)

Arguments

dt

data.frame containing the data to plot.

bars

Name of the column containing the different groups.

value

Name of the columns to use as value on the y axis of the plot. If NULL (default), counts will be used.

break_bars_by

Name of the categorical variable used to break each bar

up_to_n_bars

Plot up to this number of bars. If there are more distinct values in 'bars', the function will summarise them into an 'Others' category. Default is 20.

horizontal

Plot the bars horizontally. Default is FALSE.

sort_by_value

Sort the bars by value. Default is FALSE unless horizontal is TRUE.

sort_decreasing

Sort the values decreasingly. Default is TRUE, but sort_by_value must also be TRUE.

ggtheme

ggplot2 theme function to apply. Default is ggplot2::theme_minimal.

x_axis_label

Label for the x axis.

y_axis_label

Label for the y axis.

plot_palette

Character vector of hex codes specifying the colors to use on the plot.

plot_palette_generator

Palette from the viridis package used in case plot_palette is unspecified or insufficient for the number of colors required

static

If TRUE (or if the dataset is over 10,000 rows), the output will be static ggplot chart instead of an interactive ggplotly chart. Default is FALSE.

Value

A plotly-ized version of a ggplot bar plot.

Examples

make_barplot(dt = iris, bars = 'Species', value = 'Sepal.Length')
make_barplot(dt = ggplot2::mpg,
             bars = 'manufacturer',
             break_bars_by = 'model',
             value = 'cty',
             horizontal = TRUE,
             sort_by_value = TRUE)
