plot.hdchangeseq: Plot function for 'hdchangeseq' class

Description

Visualising the high-dimensional time series in an 'hdchangeseq' class object. The data matrix or its mean structure is visualised using a grid of coloured rectangles with colours corresponding to the value contained in corresponding coordinates. A heat-spectrum (red to white for values low to high) is used to convert values to colours.

Usage

Examples

# NOT RUN {
n <- 2000; p <- 200; ks <- 40; zs <- c(500,1000,1500)
varthetas <- c(0.1,0.15,0.2); overlap <- 0.5
obj <- multi.change(n, p, ks, zs, varthetas, overlap)
plot(obj, noise = TRUE)
# }
