Resolve the effective type of a column, respecting config overrides

Returns the type for col from the column_types map in config if one is set, otherwise falls back to infer_col_type. Use this in custom check scripts instead of calling infer_col_type() directly so that type overrides are respected.

Usage

resolve_col_type(col, x, config)

Arguments

col

Character. Column name.

x

Character vector. The column's values (as read from the file).

config

Named list. Merged configuration as returned by load_config.

Value

A single character string: "date", "numeric", "character", or "unknown".

Examples

cfg_dir <- system.file("demonstrations/config", package = "dqcheckr")
cfg <- load_config("starwars_csv", config_dir = cfg_dir)
resolve_col_type("name", c("Luke", "Leia", "Han"), cfg)   # "character"
#> [1] "character"
