Raster correlation
Performs a simple moving window correlation between two rasters
rasterCorrelation(x, y, s = 3, type = "pearson", file.name = NULL, ...)
x |
raster class object for x |
y |
raster class object for y |
s |
Scale of window. Can be a single value, two values for uneven window or a custom matrix. Must be odd number (eg., s=3, for 3x3 window or s=c(3,5) for 3 x 5 window) |
type |
Type of output, options are: "pearson", "spearman", |
file.name |
Name of output raster (optional) |
... |
Additional arguments passed to writeRaster |
raster class object or raster written to disk
