plot.CompareClassification: plot a comparison of two classification rasters

In greenbrown: Land Surface Phenology and Trend Analysis

Description

This function takes an object of class CompareClassification as input and plots a map of the class agreement of two classifications.

Usage

## S3 method for class 'CompareClassification'
plot(x, 
    xlab = "", ylab = "", 
    main = "Classification agreement", 
    names = NULL, ul = "burlywood4", 
    lr = "darkgreen", 
    ll = "khaki1", ur = "royalblue1", 
    ctr = "gray87", mar = NULL, 
    ...)

Arguments

x	Object of class CompareClassification.
xlab	A title for the x axis
ylab	A title for the y axis
main	A title for the plot
names	a list with names of the two classifications and class names. See example section for details.
ul	starting color in the upper left corner of the ColorMatrix
lr	ending color in the lower right corner of the ColorMatrix
ll	starting color in the lower left corner of the ColorMatrix
ur	ending color in the upper right corner of the ColorMatrix
ctr	color in the center of the ColorMatrix
mar	plot margins
...	Further arguments that can be passed plot.default

Examples

# # calculate trends with two different methods
# AATmap <- TrendRaster(ndvimap, start=c(1982, 1), freq=12, method="AAT", breaks=0)
# plot(AATmap)
# STMmap <- TrendRaster(ndvimap, start=c(1982, 1), freq=12, method="STM", breaks=0)
# plot(STMmap)
# 
# # classify the trend estimates from the two methods into 
# # positive, negative and no trend
# AATmap.cl <- TrendClassification(AATmap)
# plot(AATmap.cl, col=brgr.colors(3))
# STMmap.cl <- TrendClassification(STMmap)
# plot(STMmap.cl, col=brgr.colors(3))
# 
# # compare the two classifications
# compare <- CompareClassification(x=AATmap.cl, y=STMmap.cl, 
# 	names=list('AAT'=c("Br", "No", "Gr"), 'STM'=c("Br", "No", "Gr")))
# compare
# 
# # plot the comparison
# plot(compare)
