Well, it seems that it is not working as expected xD.
There might be an issue with the underlying derivate code. Right now I'm a bit busy with real life stuff, so I cannot promise a quick fix (:disappointed:) but I wanted to acknowledge that I've seen your issue.
from metr.
This is now fixed in the development version. Thanks!
library(metR)
# Curvature (Laplacian)
# Note the different boundary conditions for each dimension
variable <- expand.grid(lon = seq(0, 360, by = 3)[-1],
lat = seq(-90, 90, by = 3))
variable$z <- with(variable, cos(lat*pi/180*3) + sin(lon*pi/180*2))
variable <- cbind(
variable,
as.data.frame(Derivate(z ~ lon + lat, data = variable,
cyclical = c(TRUE, FALSE), order = 2)))
variable$lap <- Laplacian(z ~ lon + lat, cyclical = c(TRUE, FALSE), data = variable)
library(ggplot2)
ggplot(variable, aes(lon, lat)) +
geom_contour(aes(z = z)) +
geom_contour(aes(z = z.ddlon + z.ddlat), color = "red") +
geom_contour(aes(z = lap), color = "magenta")
#> Warning: Removed 480 rows containing non-finite values (`stat_contour()`).
