trmmCompose: Compositing function for TRMM data

In loicdtx/trmm: Set of utilities to work with data from the Tropical Rainfall Measuring Mission (TRMM).

Description

Creates composites that can be matched with each others from one year to the other. The same way that MODIS composites work. It differs from timeAggregate by the fact that aggregated periods can be matched between years. However, warning because the last composite of the year is likely to be truncated (particularly relevant in case of cumulative value composite, which is the default here)

Usage

trmmCompose(x, dates, by, FUN = sum, ...)

Arguments

x	filename, rasterStack, rasterBrick, or list of rasterLayers (filenames)
dates	A date vector (See trmm2date to extract dates from trmm filenames)
by	Numeric. The lenght of the composite in days
FUN	The compositing function
...	Arguments to be passed to writeRaster

Value

A RasterStack with time written to the z dimension
