The R package toOrdinal contains a single function toOrdinal that converts a cardinal number (e.g., 9) into its ordinal counterpart (e.g., 9th). Because such conversions are language specific, the conversions are specific to a supported language. At present, the package implements English, French, German, Spanish, and Swedish. For example,

  • English: toOrdinal(1) returns '1st'
  • German: toOrdinal(1, language="German") returns '1te'
  • French: toOrdinal(1, language="French") returns '1re'
  • Spanish: toOrdinal(1, language="Spanish") returns '1.er'
  • Swedish: toOrdinal(1, language="Swedish") returns '1:a'
