plot.FDboost

Plot the fit or the coefficients of a boosted functional regression model

Description

Takes a fitted FDboost-object produced by FDboost() and plots the fitted effects or the coefficient-functions/surfaces.

Usage

## S3 method for class 'FDboost'
plot(
  x,
  raw = FALSE,
  rug = TRUE,
  which = NULL,
  includeOffset = TRUE,
  ask = TRUE,
  n1 = 40,
  n2 = 40,
  n3 = 20,
  n4 = 11,
  onlySelected = TRUE,
  pers = FALSE,
  commonRange = FALSE,
  ...
)

plotPredicted(
  x,
  subset = NULL,
  posLegend = "topleft",
  lwdObs = 1,
  lwdPred = 1,
  ...
)

plotResiduals(x, subset = NULL, posLegend = "topleft", ...)

Arguments

`x`	a fitted `FDboost`-object
`raw`	logical defaults to `FALSE`. If `raw = FALSE` for each effect the estimated function/surface is calculated. If `raw = TRUE` the coefficients of the model are returned.
`rug`	when `TRUE` (default) then the covariate to which the plot applies is displayed as a rug plot at the foot of each plot of a 1-d smooth, and the locations of the covariates are plotted as points on the contour plot representing a 2-d smooth.
`which`	a subset of base-learners to take into account for plotting.
`includeOffset`	logical, defaults to `TRUE`. Should the offset be included in the plot of the intercept (default) or should it be plotted separately.
`ask`	logical, defaults to `TRUE`, if several effects are plotted the user has to hit Return to see next plot.
`n1`	see below
`n2`	see below
`n3`	n1, n2, n3 give the number of grid-points for 1-/2-/3-dimensional smooth terms used in the marginal equidistant grids over the range of the covariates at which the estimated effects are evaluated.
`n4`	gives the number of points for the third dimension in a 3-dimensional smooth term
`onlySelected,`	logical, defaults to `TRUE`. Only plot effects that where selected in at least one boosting iteration.
`pers`	logical, defaults to `FALSE`, If `TRUE`, perspective plots (`persp`) for 2- and 3-dimensional effects are drawn. If `FALSE`, image/contour-plots (`image`, `contour`) are drawn for 2- and 3-dimensional effects.
`commonRange`	logical, defaults to `FALSE`, if `TRUE` the range over all effects is the same (does not affect perspecitve or image plots).
`...`	other arguments, passed to `funplot` (only used in plotPredicted)
`subset`	subset of the observed response curves and their predictions that is plotted. Per default all observations are plotted.
`posLegend`	location of the legend, if a legend is drawn automatically (only used in plotPredicted). The default is "topleft".
`lwdObs`	lwd of observed curves (only used in plotPredicted)
`lwdPred`	lwd of predicted curves (only used in plotPredicted)
