count_months: Count Number of Months in Climate Mask Layers

In rebeccalpowell/grassmapr: Predict C3/C4 Grass Distribution

Description

Generates raster layer of counts corresponding to number of times (usually months) each grid cell satisfies climate criteria (e.g., growing-season or C4 climate).

Usage

count_months(climate.mask, filename = "", ...)

Arguments

climate.mask	Raster* object. Mask of grid cells that meet climate parameters, may be result of intersect_masks or mask_grids. Object should be multi-layer (i.e., multi-date).
filename	Character. Optional output root filename passed to writeRaster, default output file type is GeoTiff. If not specified, output is written to a temporary file.
...	Other arguments passed to writeRaster.

Value

RasterLayer. Values correspond to number of months (or other temporal unit) that grid cell meets minimum climate parameters.

See Also

mask_climate, mask_grids, intersect_masks, sum.

Examples

# Count number of months each grid cell meets C4 climate criteria

# For this example, annual stack of monthly C4 climate masks were generated
#   using mask_climate()
C4_month_total <- count_months(C4_mask)

# Plot monthly totals
plot(C4_month_total)
