map_indices: Map indices

In oeli: Utilities for Developing Data Science Software

Map indices

Description

This function maps indices from an input vector to corresponding sequences of grouped indices. Each element from the input specifies a group to be mapped from the sequence, determined by the grouping size n.

Usage

map_indices(indices, n)

Arguments

indices	[integer()] An index vector, where each element specifies a group to be mapped from the sequence.
n	[integer] The size of each group of consecutive indices.

Details

This function is useful when working with indices arranged in fixed-size groups, where each group can be referenced by a single index. For example, if indices are structured in chunks of 3, calling this function with n = 3 will map the corresponding groups of 3 consecutive indices for the given input indices, see the examples.

Value

An integer vector, containing the mapped indices according to the specified group size.
