Conveniently plot basic India map

Usage

plot_india(
  regions = c("states", "state", "districts", "district"),
  include = c(),
  exclude = c(),
  data = data.frame(),
  values = "values",
  theme = theme_map(),
  labels = FALSE,
  label_color = "black",
  label_size = 4,
  ...
)

Arguments

regions

The region breakdown for the map, can be one of ("states", "state", "districts", "district"). The default is "states".

include

The regions to include in the resulting map. If regions is "states"/"state", the value can be either a state name, abbreviation or code. For districts, the district codes must be provided as there can be multiple districts with the same name. If states are provided in the districts map, only districts in the included states will be returned.

exclude

The regions to exclude in the resulting map. If regions is "states"/"state", the value can be either a state name, abbreviation or code. For districts, the district codes must be provided as there can be multiple districts with the same name. The regions listed in the include parameter are applied first and the exclude regions are then removed from the resulting map. Any excluded regions not present in the included regions will be ignored.

data

A data frame containing values to plot on the map. This parameter should be a data frame consisting of two columns, a code (2 characters for state, 3 characters for district) and the value that should be associated with that region. The columns of data must be code or state and the value of the `values` parameter.

values

The name of the column that contains the values to be associated with a given region. The default is "value".

theme

The theme that should be used for plotting the map. The default is theme_map from ggthemes.

labels

Whether or not to display labels on the map. Labels are not displayed by default.

label_color

The color of the labels to display. Corresponds to the color option in the [ggplot2::aes()] mapping. The default is "black".

label_size

The size of the labels to display. Corresponds to the size option in the [ggplot2::aes()] mapping. The default is 4. for more color options.

...

Other arguments to pass to [ggplot2::aes()]. These are often aesthetics, used to set an aesthetic to a fixed value, like color = "red" or linewidth = 3. They affect the appearance of the polygons used to render the map (for example fill color, line color, line thickness, etc.). If any of color/colour, fill, or linewidth are not specified they are set to their default values of color="black", fill="white", and linewidth=0.4.

Value

A [ggplot2::ggplot] object that contains a basic US map with the described parameters. Since the result is a ggplot object, it can be extended with more [ggplot2::Geom] layers, scales, labels, themes, etc.
