This is a selector checker function intended for use as parameter selector_checker in a call to the function Start() in the package 'startR'. This function complies with the input/output interface required by Start() defined in the documentation for the parameter selector_checker of that function.
SelectorChecker(selectors, var = NULL, return_indices = TRUE, tolerance = NULL)Numeric indices or variable values to be retrieved for a dimension, automatically provided by Start(). See details in the documentation of the parameters selector_checker and … of the function Start(). The indices or values can be provided in the form of a vector or in the form of a list with two elements.
Vector of values of a coordinate variable where to search matches with the provided indices or values in the parameter selectors, automatically provided by Start(). See details in the documentation of the parameters selector_checker and … of the function Start(). The parameter var is optional. When not specified, SelectorChecker simply returns the input indices.
Boolean flag, automatically configured by Start(), telling whether to return numeric indices or coordinate variable values after doing the matching.
Numeric value with a tolerance value to be used in the matching of the selectors and var. See documentation on <dim_name>_tolerance in …, in the documentation of the function Start().
A vector of either the indices of the matching values (if return_indices = TRUE) or the matching values themselves (if return_indices = FALSE).
