a GAM model with smooths created using the mgcv package

filled

logical value to indicate whether a filled plot should be created (TRUE) or not (FALSE)

outline

the name of an sf object to be plotted (NULL is the default)

Examples

library(mgcv)
library(ggplot2)
library(dplyr)
library(metR)
library(cowplot)
set.seed(2) ## simulate some data...
dat <- gamSim(1,n=400,dist="normal",scale=2)
# use x1 and x2 as the coordinates
b <- gam(y~s(x0, x1, bs = 'gp', by = x2),data=dat)
plot_2d_smooth(b, filled = TRUE)
