an optional list used by selected plot
functions to create
custom axes
. If this axes
argument is not
NULL
, functions plot.basisfd
, plot.fd
,
plot.fdSmooth
plotfit.fd
, plotfit.fdSmooth
, and
plot.Lfd
will create axes via x$axes[[1]]
and
x$axes[-1]
. The primary example of this uses
list("axesIntervals", ...)
, e.g., with Fourier
bases
to create CanadianWeather
plots
