preplot.locfit {locfit} | R Documentation |
preplot(object, newdata, se.fit=F, deriv, tr, what, get.data=F, f3d=F)
object |
Fitted object from locfit() .
|
newdata |
Points to predict at. Can be given in several forms: vector/matrix; list, data frame. |
se.fit |
If TRUE , standard errors are computed along with the fitted values.
|
deriv |
vector to control prediction and plotting of derivatives. E.g.
deriv=1 for the local slope; deriv=c(1,1) for local curvature.
|
tr |
Transformation for likelihood models. Default is the inverse of the link function. |
what |
What to predict/plot. Default is coef (the local fit). Other choices
are infl (influence function); nlx (length of weight diagram);
band (bandwidth); degr (local polynomial degree).
|
get.data |
If TRUE , the original data is attached to the returned object, and
added to the plot.
|
f3d |
If TRUE , forces a trellis plot.
|
An object with class "locfitpred"
, containing the predicted
values and additional information used to construct the plot.
