Run all version comparison checks between two dataset snapshots

Runs CP-01 to CP-08 comparing a current delivery against the previous one.

Usage

run_comparison_checks(
  df_current,
  df_previous,
  config,
  types_current = NULL,
  types_previous = NULL
)

Arguments

df_current

A data frame. The current delivery.

df_previous

A data frame. The previous delivery.

config

Named list. Merged configuration as returned by load_config.

types_current, types_previous

Optional named character vectors of pre-resolved column types for the current and previous data frames (as produced by resolve_col_type per column). When NULL (the default), types are resolved once here and shared by all type-dependent comparison checks.

Value

A list of dq_result objects. The list carries attributes new_cols, dropped_cols, and type_changed_cols (character vectors) for use by the snapshot writer.

Examples

cfg_dir   <- system.file("demonstrations/config", package = "dqcheckr")
cfg       <- load_config("starwars_csv", config_dir = cfg_dir)
curr_path <- system.file("demonstrations/data2/starwars_v2.csv", package = "dqcheckr")
prev_path <- system.file("demonstrations/data2/starwars_v1.csv", package = "dqcheckr")
curr      <- read_dataset(curr_path, cfg)
prev      <- read_dataset(prev_path, cfg)
results   <- run_comparison_checks(curr, prev, cfg)
