plot.basisfd: Plot a Basis Object

In drtagkim/mcgillfdar: Functional Data Analysis

Description

Plots all the basis functions.

Usage

## S3 method for class 'basisfd'
plot(x, knots=TRUE, axes=NULL, ...)

Arguments

x	a basis object
knots	logical: If TRUE and x[['type']] == 'bslpine', the knot locations are plotted using vertical dotted, red lines. Ignored otherwise.
axes	Either a logical or a list or NULL. logical whether axes should be drawn on the plot list a list used to create custom axes used to create axes via do.call(x$axes[[1]], x$axes[-1]). The primary example of this uses list("axesIntervals", ...), e.g., with Fourier bases to create CanadianWeather plots
...	additional plotting parameters passed to matplot.

Value

none

Side Effects

a plot of the basis functions

Examples

##
## 1.  b-spline
##
# set up the b-spline basis for the lip data, using 23 basis functions,
#   order 4 (cubic), and equally spaced knots.
#  There will be 23 - 4 = 19 interior knots at 0.05, ..., 0.95
lipbasis <- create.bspline.basis(c(0,1), 23)
# plot the basis functions
plot(lipbasis)

##
## 2.  Fourier basis
##
yearbasis3 <- create.fourier.basis(c(0,365),
                    axes=list("axesIntervals") )
#  plot the basis
plot(yearbasis3)
