rain_extract_chirps: Extract daily rainfall from CHIRPS data

In hmcdevitt/spExtract: Extract values at spatial locations from Raster* objects as matrices

Description

Extract daily rainfall from CHIRPS data

Usage

rain_extract_chirps(
  rain_array,
  rain_dates,
  extent,
  resolution,
  cumrain = 0,
  coords_dates,
  coords
)

Arguments

rain_array	an array with dimensions 1 and 2 being the y and x values (respectively) of the rain raster/tiff layers, and the 3rd dimension is the multiple dates for same spatial extent. Build using build_rain_array
rain_dates	a vector of class Date containing the dates corresponding to each "layer" in the 3rd dimension of the array
extent	an extent object. contains xmin, xmax, ymin, ymax of the raster/tiff layers used to make the array
resolution	a vector with 2 values indicating the x and y resolution of each raster cell
cumrain	(defualt = 0) the number of days used to calculate the cumulative rainfall at a location
coords_dates	a vector of class Date of the dates for each of the coordinates in coords
coords	a 2 column matrix/dataframe with the x and y coordinates in same projection as extent
