plots the fitted effects or the coefficient-functions/surfaces.

no return value (plot method)
a fitted FDboost-object
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.
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.
a subset of base-learners to take into account for plotting.
logical, defaults to TRUE. Should the offset be included in
the plot of the intercept (default) or should it be plotted separately.
logical, defaults to TRUE, if several effects are plotted the user
has to hit Return to see next plot.

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.
gives the number of points for the third dimension in a 3-dimensional smooth term
logical, defaults to TRUE. Only plot effects that where
selected in at least one boosting iteration.
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.
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 of the observed response curves and their predictions that is plotted. Per default all observations are plotted.
location of the legend, if a legend is drawn automatically (only used in plotPredicted). The default is "topleft".
lwd of observed curves (only used in plotPredicted)
lwd of predicted curves (only used in plotPredicted)
FDboost for the model fit and
coef.FDboost for the calculation of the coefficient functions.
