Decrement subscript indices — index

Replaces every simple subscript index in x[i] or x[[i]] with x[i - 1L] / x[[i - 1L]]. Targets identifier and numeric literal indices; complex expressions (e.g. x[a + b]) are left untouched.

Usage

index_decrement()

Value

A Mutator object.

Examples

index_decrement()
#> Mutator: x[<i>] → x[<i> - 1L]
#> Query: [(subset arguments: (arguments (argument value: [(identifier) (float) (integer)] @index))) (subset2 arguments: (arguments (argument value: [(identifier) (float) (integer)] @index)))]
