Resolve CRU variable flags and input file paths

Source: R/internal-resolve_cru_inputs.R
dot-resolve_cru_inputs.Rd

Internal helper used by higher-level CRU readers to convert user-facing arguments (e.g., pre = TRUE, tmp = TRUE, x = <dir>) into a standardised structure containing:

Usage

.resolve_cru_inputs(pre = FALSE, tmp = FALSE, x = NULL, ...)

Arguments

pre

Logical. Whether precipitation (pre) is requested.

tmp

Logical. Whether temperature (tmp) is requested.

x

Character. Either a directory containing CRU files or one or more CRU .dat.gz file paths.

...

Ignored. Allows future expansion.

Value

A list with two elements:

vars

Named logical vector of CRU variable flags.

files

Character vector of resolved CRU file paths.

Details

  • a named logical vector of requested CRU variables (vars)

  • a character vector of file paths (files)

If x is a directory, all matching CRU files (grid_10min_*.dat.gz) inside that directory are returned. If x is one or more file paths, they are returned unchanged.

This function does not read or validate file contents; it only resolves which files should be processed downstream.
