Description
An interactive htmlwidgets of the perspective plot for gam model(s) using the package plotly.
Usage
widget_gam(
...,
formula,
newdata = data,
proj_xy = TRUE,
proj_xz = TRUE,
n = 501L,
newid = seq_len(min(3L, nrow(newdata))),
ylim = range(X[is.finite(X)], newX[is.finite(newX)]),
surface_col = c("white", "lightgreen")
)
Arguments
... |
one or more gam models based on a same data set. |
formula |
one-sided formula |
newdata |
(for future expansion) |
proj_xy |
logical scalar, whether to show
the projection to the |
proj_xz |
logical scalar, whether to show

n |
integer scalar, fineness of visualization,
default value is |
newid |
integer scalar or vector,
row indices of |
ylim |
length-2 double vector,

surface_col |
length-2 character vector, color of the integrand surface(s), for lowest and highest surface values |
Value
The function widget_gam() returns a pretty htmlwidgets created by R package plotly.
Note
The maintainer is not aware of any functionality of projection of arbitrary curves in package plotly. Currently, the projections are hard coded.
Examples
library(mgcv)
# ?gam
set.seed(2)
dat = gamSim(1, n = 400, dist = 'normal', scale = 2)
gam(y ~ s(x0) + s(x1) + s(x2) + s(x3), data = dat)
