ptw (version 1.9-15)

plot.ptw: Plot a ptw object

Description

The function plots a ptw object. It shows either the original and warped signals, or the warping function.

Usage

# S3 method for ptw
plot(x, what = c("signal", "function"),
         type = c("simultaneous", "individual"), ask = TRUE, ...)

Arguments

x

object of class 'ptw'

what

"signal" plots the reference, sample and warped sample signal(s); "function" plots the warping function as warped 'time' - 'time' for the forward warping mode and as 'time' - warped 'time' for the backward warping mode.

type

"simultaneous" plots all signals or warping functions in one plot; "individual" generates multiple plots

ask

logical, whether to ask before showing a new plot

…

further arguments to the plotting functions

Examples

# NOT RUN {
data(gaschrom)
ref <- gaschrom[1:8,]
samp <- gaschrom[9:16,]
gaschrom.ptw <- ptw(ref, samp, warp.type = "individual",
              optim.crit = "RMS", init.coef = c(0, 1, 0, 0))
plot(gaschrom.ptw)
plot(gaschrom.ptw, what = "function")
# }
