Usage

axis_entries(daf, axis, indices = NULL, allow_empty = FALSE)

Arguments

daf: A DafReader.
axis: Axis name (character scalar).
indices: Optional integer index vector (1-based). When allow_empty = TRUE, a zero or negative index is allowed and is translated to the empty string "" in the result.
allow_empty: If TRUE, treat zero/negative indices as the empty string "" in the result (mirrors Julia axis_entries(...; allow_empty=true)).

Value

Character vector.

             indices = c(3L, 0L), allow_empty = TRUE)
#> [1] "MEBEMP-L" ""
