plot.ObjFct: Plot objective functions

In ModelDataComp: Model-Data Comparison

Description

Barplot or scatterplot of objective function metrics. A barplot is created if only one metric is defined in which. A scatterplot is created if two metrics are defined.

Usage

## S3 method for class 'ObjFct'
plot(x, which = c("Cor", "KS", "AE"), alpha = 0.1, cols = "black", 
    pch = NULL, legend = TRUE, xlab = NULL, ylab = NULL, xlim = NULL, 
    ylim = NULL, txt = NULL, add = FALSE, ...)

Arguments

x	an object of class ObjFct
which	Which objective function metrics should be plotted? If one metric is defined, a barplot will be plotted. If more than one metric is defined, the first metric will be used for the x-axis and the second metric for y-axis of a scatterplot. If a third metric is specified, point sizes in the scatterplot will be scaled.
alpha	significance level to plot objetive functions that are not significant different from the optimum with different point symbols. This only works if the the selected objective functions in which have a p-value. Set to NULL to avoid this option.
cols	colors for the groups
pch	point symbols for scatterplots or for pointsplots (instead of barplot)
legend	plot a legend for the significance point symbols?
xlab	label for x-axis
ylab	label for y-axis
xlim	limits for x-axis
ylim	limits for y-axis
txt	text for the points
add	add plot to an existing plot? This only works for scatterplots.
...	further arguments to plot

Examples

# create some data
obs <- 1:300
sim <- obs * c(rnorm(100, 1, 0.1), rnorm(100, 1, 0.3), rnorm(100, 1, 0.5))
groups <- c(rep("subset 1", 100), rep("subset 2", 100), rep("subset 3", 100))
ScatterPlot(sim, obs, groups, objfct=TRUE)

of <- ObjFct(sim, obs, groups)
of 

# default plot
plot(of)

# barplots with only one metric
plot(of, "Cor")
plot(of, "AE")
plot(of, "MEF")

# options for the scatterplot:
plot(of, c("Cor", "RMSE", "MEF"))
plot(of, c("Spearman", "KS"), alpha=0.05)
plot(of, c("Spearman", "KS"), alpha=NULL)
plot(of, cols=c("black", "red", "blue", "green"))
plot(of, c("Cor", "FV"), pch=0:4)
