plot.ptw {ptw} | R Documentation |
The function plots a ptw
object. It shows either the original and
warped signals, or the warping function.
## S3 method for class 'ptw': plot(x, what = c("signal", "function"), type = c("simultaneous", "individual"), ask = TRUE, ...)
x |
object of class 'ptw' |
what |
"signal" plots the reference, sample and warped
sample signal(s); "function" plots the warping function |
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 |
