Coding style conventions

Following conventions apply to the easystats-ecosystem, to ensure that function and argument names as well as element names for return-values follow a consistent pattern across all packages.

Element / Column names (for returned data frames)

  1. First letter of the column name is capital, unless (6) applies (example: Parameter).

  2. First letter of nouns is capital, unless (6) applies (example: ROPE_Percentage, Prior_Scale).

  3. Using underscore rather than camelCase to separate words (example: CI_high).

  4. Multiple words: common/main part first and adjective/specifier/variational part after, unless (8) applies (example: Median_standardized, ROPE_percentage).

  5. Abbreviations: all uppercase (example: ESS, MCSE, ROPE).

  6. Keep conventions for reserved words (example: p, pd, Rhat).

  7. Adjectives / verbs: all lower case, unless (1) applies (example: high or low in CI_high or CI_low).

  8. In case of multiple occurrences of column names that indicate the same measure or content (like CI_low or SE), the common part is appended as suffix to the context specific part (example: CI_low and Eta2_partial_CI_low, and not CI_low and CI_low_Eta2_partial).

  9. The “squared” term in column names that refers to “common” statistics (Eta2, Chi2, Omega2, …) should be written as 2, not sq, squared or pétit-deux (example: Chi2, and not Chisq, Eta2, and not Eta_squared). This rule does not apply to function names.
