Normalize R Data Types to DuckDB Types for Tabix

Description

Normalizes R data type names to their corresponding DuckDB types for use with tabix readers. This function handles common R type name variations and maps them to appropriate DuckDB column types.

Usage

normalize_tabix_types(types)

Arguments

types

A character vector of R data type names to be normalized.

Details

The function performs the following normalizations:

• Integer types (integer, int, int32, int64) -> BIGINT

• Numeric types (numeric, double, float) -> DOUBLE

• Character types (character, string, chr) -> VARCHAR

• Logical types (logical, bool, boolean) -> BOOLEAN

• Other types -> Converted to uppercase as-is

If an empty vector is provided, it returns the empty vector unchanged.

Value

A character vector of normalized DuckDB type names suitable for tabix columns.
