plot_dot {COINr}R Documentation

Dot plots of single indicator with highlighting

Description

Plots a single indicator as a line of dots, and optionally highlights selected units and statistics. This is intended for showing the relative position of units to other units, rather than as a statistical plot. For the latter, use plot_dist().

Usage

plot_dot(
  coin,
  dset,
  iCode,
  Level = NULL,
  ...,
  usel = NULL,
  marker_type = "circle",
  add_stat = NULL,
  stat_label = NULL,
  show_ticks = TRUE,
  plabel = NULL,
  usel_label = TRUE,
  vert_adjust = 0.5
)

Arguments

coin

The coin

dset

The name of the data set to apply the function to, which should be accessible in .$Data.

iCode

Code of indicator or aggregate found in dset. Required to be of length 1.

Level

The level in the hierarchy to extract data from. See get_data().

...

Further arguments to pass to get_data(), other than those explicitly specified here.

usel

A subset of units to highlight.

marker_type

The type of marker, either "circle" (default) or "cross", or a marker number to pass to ggplot2 (0-25).

add_stat

A statistic to overlay, either "mean", "median" or else a specified value.

stat_label

An optional string to use as label at the point specified by add_stat.

show_ticks

Set FALSE to remove axis ticks.

plabel

Controls the labelling of the indicator. If NULL (default), returns the indicator code. Otherwise if "iName", returns only indicator name, if "iName+unit", returns indicator name plus unit (if found), if "unit" returns only unit (if found), otherwise if "none", displays no text. Finally, any other string can be passed, so e.g. "My indicator" will display this on the axis.

usel_label

If TRUE (default) also labels selected units with their unit codes. FALSE to disable.

vert_adjust

Adjusts the vertical height of text labels and stat lines, which matters depending on plot size. Takes a value between 0 to 2 (higher will probably remove the label from the axis space).

Details

This function uses ggplot2 to generate plots, so the plot can be further manipulated using ggplot2 commands. See ⁠vignette("visualisation⁠) for more details on plotting.

This function replaces the now-defunct plotIndDot() from COINr < v1.0.

Value

A ggplot2 plot object.

Examples

# build example coin
coin <- build_example_coin(up_to = "new_coin")

# dot plot of LPI, highlighting two countries and with median shown
plot_dot(coin, dset = "Raw", iCode = "LPI", usel = c("JPN", "ESP"),
         add_stat = "median", stat_label = "Median", plabel = "iName+unit")
