Helper function that returns names and descriptions of STICS output variables from a partial name and/or descriptive keywords.
get_var_info(var = NULL, keyword = NULL, stics_version = "latest")Vector of variable names (or partial names). Optional, if not provided, the function returns information for all variables.
Search by keyword instead of variable name (search in the name and description field)
Name of the STICS version. Optional, can be used
to search parameters information relative to a specific STICS version.
By default the latest version returned by get_stics_versions_compat()
is used.
A data.frame with information about variable(s) with columns
name, definition, unit, type
The function understand regex as input.
