In steingod/R-mipolsat: Useful functions for handling locally processed satellite data

Description

This function reads the output from readAVHRR and creates an image on the graphical device used. Some basic channel combination is also supported.

Usage

createAVHRRimage(x, channel=1, map=TRUE, method="N", ...)  

Arguments

x	R object (list) returned by readAVHRR
channel	channel identification
map	logical telling whether coast lines should be added
method	letter specifying how to combine channels ("D" is difference, "R" is ratio, "N" is none)
colorspace	vector of the type c("blue","yello", "red") that is interpolated to a palette. Use colors() to check which colornames that are defined, colorRampPalette is used to create the palette
