ffpcplot: Plot PC-based function-on-function regression terms

Description

Convenience function for graphical summaries of ffpc-terms from a pffr fit.

Usage

ffpcplot(object, type = c("fpc+surf", "surf", "fpc"),
    pages = 1, se.mult = 2, ticktype = "detailed",
    theta = 30, phi = 30, plot = TRUE, auto.layout = TRUE)

Arguments

object

a fitted pffr-model

type

one of "fpc+surf", "surf" or "fpc": "surf" shows a perspective plot of the coefficient surface implied by the estimated effect functions of the FPC loadings, "fpc" shows three plots: 1) a scree-type plot of the estimated eigenvalues of the functio

se.mult

display estimated coefficient functions associated with the FPC loadings with plus/minus this number time the estimated standard error. Defaults to 2.

pages

the number of pages over which to spread the output. Defaults to 1. (Irrelevant if auto.layout=FALSE.)

ticktype

see persp.

theta

see persp.

phi

see persp.

plot

produce plots or only return plotting data? Defaults to TRUE.

auto.layout

should the the function set a suitable layout automatically? Defaults to TRUE

Value

• primarily produces plots, invisibly returns a list containing the data used for the plots.
