temporal_sync_raster: Temporally Sync Rasters

In climstats: R functions for working with station and gridded climate data.

Description

Aligns ("syncs") a Raster to a reference Raster.

Usage

  temporal_sync_raster(unsynced, reference,
    synctype = "by.month", unsynced_dates, reference_dates,
    verbose = FALSE)

Arguments

unsynced	A raster object or a string pointing to a raster on disk to be temporally synced to a reference file.
reference	A raster object with reference zvalue dates specific to the month and year.
synctype	Type of temporal sync; options are "by.month" or "by.year.month".
unsynced_dates	Required if getZ(unsynced) does not provide dates for unsynced raster.
reference_dates	Required if getZ(reference) does not provide reference dates for reference raster.
verbose	verbose=TRUE will print process information.

Details

Matches the temporal resolution and extent of the unsynced raster object to the reference raster object. Files with 12 layers (1/month) are expanded to multiple years using "by.month". Files with unique entries per month per year are reduced to the temporal range of the reference object using "by.year.month".

Value

Returns a RasterLayer, RasterBrick or RasterStack object.
