Get indices of entries in an axis

Returns the integer indices for specified entry names along an axis.

Usage

axis_indices(daf, axis, entries, allow_empty = FALSE)

Arguments

daf

A Daf object

axis

Name of the axis

entries

Character vector of entry names to look up

allow_empty

Whether to allow empty entries (return -1 for empty strings if TRUE)

Value

A vector of 1-based indices corresponding to the entries

Details

This function maps names to their position indices along the axis. If allow_empty is TRUE, empty strings are converted to index -1. Indices in R are 1-based (first element has index 1), consistent with R conventions. See the Julia documentation for details.
