scaleSatin: Spatial re-scaling of satellite data

In r-forge/satin: Functions for downloading, reading and displaying satellite data for oceanographic applications with R

Description

This function down-scales satellite data by quadrants of user defined size (in degrees), calculating the value given by a function.

Usage

scaleSatin(satin.obj, extent = 1, FUN = mean, format = "wide")

Arguments

satin.obj	satin object as returned by read.oceancolor
extent	size in degrees of the squared quadrant for the summary
FUN	summary function, defaults to mean
format	Default is format = "wide", producing a satin object suitable for creating a map with plotSatin. When format = "long", a four column data frame with longitude, latitude, period and parameter values is produced.

Value

If format = "wide" (the default), a satin object as produced by read.oceancolor.

If format="long", a data frame with columns: longitude, latitude, period and parameter values.
