Examples

# \donttest{
set.seed(2021)
d <- data.frame(
  X = runif(1000), Y = runif(1000),
  year = sample(1:10, size = 1000, replace = TRUE)
)
d$density <- rnorm(0.01 * d$X - 0.001 * d$X * d$X + d$Y * 0.02 - 0.005 * d$Y * d$Y, 0, 0.1)
m <- mgcv::gam(density ~ 0 + as.factor(year) + s(X, Y), data = d)
d$resid <- resid(m)
# the default names match, with the exception of year -- so change it
resid_time(d, time = "year")
