LAPOP Cross-Country Bar Graphs — lapop

This function creates bar graphs for comparing values across countries using LAPOP formatting.

Usage

lapop_ccm(
  data,
  pais = data$pais,
  outcome_var = data$prop,
  lower_bound = data$lb,
  upper_bound = data$ub,
  label_var = data$proplabel,
  var = data$var,
  ymin = 0,
  ymax = 100,
  lang = "en",
  main_title = "",
  source_info = "",
  subtitle = "",
  sort = "",
  y_label = "",
  x_label = "",
  highlight = "",
  color_scheme = c("#784885", "#008381", "#C74E49"),
  label_size = 4,
  text_position = 0.7
)

Arguments

data: Data Frame. Dataset to be used for analysis. The data frame should have columns titled pais (values of x-axis variable (usually pais); character vector), prop (outcome variable; numeric), proplabel (text of outcome variable; character), lb (lower bound of estimate; numeric), ub (upper bound of estimate; numeric), and var (labels of secondary variables; character). Default: None (must be supplied).
pais, outcome_var, label_var, lower_bound, upper_bound, var: Character, numeric, character, numeric, numeric, character. Each component of the plot data can be manually specified in case the default columns in the data frame should not be used (if, for example, the values for a given variable were altered and stored in a new column).
ymin, ymax: Numeric. Minimum and maximum values for y-axis. Default: 0 to 100.
lang: Character. Changes default subtitle text and source info to either Spanish or English. Will not translate input text, such as main title or variable labels. Takes either "en" (English) or "es" (Spanish). Default: "en".
main_title: Character. Title of graph. Default: None.
source_info: Character. Information on dataset used (country, years, version, etc.), which is added to the end of "Source: " in the bottom-left corner of the graph. Default: None (only "Source: " will be printed).
subtitle: Character. Describes the values/data shown in the graph, e.g., "percentage of Mexicans who say...)". Default: None.
sort: Character. Method of sorting bars. Options: "var1" (highest to lowest on variable 1), "var2" (highest to lowest on variable 2), "var3" (highest to lowest on variable 3), "alpha" (alphabetical along x-axis/pais). Default: Order of data frame.
y_label: Character. Y-axis label.
x_label: Character. X-axis label.
highlight: Character. Country of interest. Will highlight (make darker) that country's bar. Input must match entry in "vallabel" exactly. Default: None.
color_scheme: Character. Color of bars. Takes hex number, beginning with "#". Default: "#784885", "#008381", "#C74E49".
label_size: Numeric. Size of text for data labels (percentages above bars). Default: 4.
text_position: Numeric. Amount that text above error bars should be offset (to avoid overlap). Default: 0.7

Value

Returns an object of class ggplot, a ggplot figure showing average values of some variables across multiple countries.
