plot.gfpop: plot.gfpop

In gfpop: Graph-Constrained Functional Pruning Optimal Partitioning

plot.gfpop

Description

Plotting inferred segment parameters (the result of gfpop) and data.

Usage

## S3 method for class 'gfpop'
plot(x, ..., data, multiple = TRUE)

Arguments

x	a gfpop class object
...	Other parameters
data	the data from which we get the gfpop result
multiple	if TRUE we plot data and the model on different graphs. Only with "mean" and "poisson" cost functions (as in that case the parameter values represent the data mean value over each segment) we allow the User to plot signal and data on a single graph.

Value

plot data and the inferred gfpop segments

Examples

n <- 1000 #data length
data <- dataGenerator(n, c(0.3, 0.4, 0.7, 0.95, 1), c(1, 3, 1, -1, 4), "mean", sigma = 3)
myGraph <- graph(type = "relevant", gap = 0.5, penalty = 2 * sdDiff(data) ^ 2 * log(n))
g <- gfpop(data, myGraph, type = "mean")
plot(x = g, data = data, multiple = FALSE)

data <- dataGenerator(n, c(0.4, 0.8, 1), c(1, 1.7, 2.3), "exp")
g <- gfpop(data,graph(type = "isotonic", penalty = 2 * sdDiff(data) ^ 2 * log(n)), type = "exp")
plot(x = g, data = data, multiple = TRUE)

data <- dataGenerator(n, c(0.22, 0.75, 1), c(1.4,1,0.8), "poisson")
g <- gfpop(data, paperGraph(8), type = "poisson")
plot(x = g, data = data, multiple = TRUE)
