layer
February 2, 2025 · View on GitHub
The goal of layer is to simplify the whole process of creating stacked
tilted maps, that are often used in scientific publications to show
different environmental layers for a geographical region. Tilting maps
and layering them allows to easily draw visual correlations between
these environmental layers.
Something in the line of:

Installation
You can install the development version of layer from GitHub with:
# install.packages("remotes")
remotes::install_github("marcosci/layer")
Example
This is a basic example which shows you how to solve a common problem:
library(layer)
tilt_landscape_1 <- tilt_map(landscape_1)
tilt_landscape_2 <- tilt_map(landscape_2, x_shift = 25, y_shift = 50)
tilt_landscape_3 <- tilt_map(landscape_3, x_shift = 50, y_shift = 100)
tilt_landscape_points <- tilt_map(landscape_points, x_shift = 75, y_shift = 150)
map_list <- list(tilt_landscape_1, tilt_landscape_2, tilt_landscape_3, tilt_landscape_points)
plot_tiltedmaps(map_list,
layer = c("value", "value", "value", NA),
palette = c("bilbao", "mako", "rocket", NA),
color = "grey40")

More advanced example
Some more realistic looking data (DEM, drought, precipitation, and wildfires for continental USA):
tilt_landscape_1 <- tilt_map(dem_usa, y_tilt = 3)
tilt_landscape_2 <- tilt_map(drought_usa, y_tilt = 3, x_shift = 15, y_shift = 25)
tilt_landscape_3 <- tilt_map(prec_usa, y_tilt = 3, x_shift = 30, y_shift = 50)
tilt_landscape_4 <- tilt_map(fire_usa, y_tilt = 3, x_shift = 45, y_shift = 65)
map_list <- list(tilt_landscape_1, tilt_landscape_2, tilt_landscape_3, tilt_landscape_4)
plot_tiltedmaps(map_list, palette = c("tofino", "rocket", "mako", "magma"), direction = c(-1, 1, 1, 1))
