Collection of R functions to render minimal maps using ggplot.
This project is not a R package and thus cannot be installed. To use this project, clone the repository and run renv::install() to install necessary packages / dependencies (if you do not have rev installed yet, you might have to run install.packages("renv") first and restart your R session). To quickly render a map, simply run the following snippet of code with the working directory set to this repository.
# This will load all included functions & packages source("load.R") # Download mapdata if (!file.exists(get_cache_path("amsterdam_example", type = "boundingbox"))) { # Example bounding box of central Amsterdam boundingbox <- st_bbox(c(xmin = 4.861836, ymin = 52.340088, xmax = 4.934535, ymax = 52.401469)) # This will download the data and automatically write it into a cache file # so as to not overload the free OpenStreetMaps API. All the cached files # can be found in data/cache in the directory of this repository. download_mapdata(data_id = "amsterdam_example", boundingbox = boundingbox) } # Load the data from cache mapdata <- load_mapdata("amsterdam_example") # Render the final map (this function has options for recoloring etc.) render_map(mapdata) 
There is also a convenience function to render a full pdf ready for printing in DIN A1 size. If you want to create your own poster it might be a good start to just copy and adjust this function to your liking (or just use it as is!).
# Generate pdf for printing full_render_to_pdf( mapdata, name = "Amsterdam, Noord-Holland, Netherlands", filename = "example.pdf", dir = "README_files" ) The resulting PDF can be found here.
