vec_read_time_slice

R Documentation

Read a single time slice from a .vec time cube

Description

Performs a linear scan of the index for tiles with time == time and decodes the matching window. The lookup is O(n_tiles) per call — Phase 6's optimized hash-map lookup is a follow-up.

Usage

vec_read_time_slice(r, time, band = 1L, level = 0L, cols = NULL, rows = NULL)

Arguments

`r`	A `vectra_raster` from `vec_open_raster()`.
`time`	Time value to match (numeric/integer).
`band`	Band index (1-based).
`level`	Overview level. Default 0.
`cols`, `rows`	1-based ranges, same as `vec_read_window`.
