get_party_color: Extract party color from Wikipedia

In partycoloR: Extract Party Colors and Logos from Wikipedia

Extract party color from Wikipedia

Description

Extracts the primary party color (or all colors) from a political party's English Wikipedia page. The function scrapes the party infobox for color information.

Usage

get_party_color(url, all_colors = FALSE, normalize = TRUE)

Arguments

url	A character vector of Wikipedia URLs for political party pages.
all_colors	Logical. If 'FALSE' (default), returns only the first/primary color. If 'TRUE', returns all colors as a list.
normalize	Logical. If 'TRUE' (default), attempts to normalize color values to uppercase hex codes. Named colors (e.g., "red") are converted to hex codes.

Details

The function works by scraping the Wikipedia infobox (vcard table) for spans with background-color style attributes. This depends on Wikipedia's current HTML structure and may occasionally fail if the page structure changes.

For use with 'dplyr::mutate()', this function is vectorized over the 'url' argument. Each URL is processed independently.

Value

If 'all_colors = FALSE', a character vector of hex color codes (or NA for failed extractions). If 'all_colors = TRUE', a list of character vectors containing all colors for each URL.

Examples

if (curl::has_internet()) {
  # Single party
  get_party_color("https://en.wikipedia.org/wiki/Democratic_Party_(United_States)")

  # Multiple parties
  urls <- c(
    "https://en.wikipedia.org/wiki/Democratic_Party_(United_States)",
    "https://en.wikipedia.org/wiki/Republican_Party_(United_States)"
  )
  get_party_color(urls)

  # Get all colors (some parties have multiple)
  get_party_color(urls, all_colors = TRUE)
}
