plot.basisfd {fda} | R Documentation |
Plots all the basis functions.
## S3 method for class 'basisfd': plot(x, knots=TRUE, axes=NULL, ...)
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 .
|
... |
additional plotting parameters passed to matplot .
|
none
a plot of the basis functions
## ## 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)
