))
# Install the package
install.packages("rrstools")Using pak
# install.packages("pak")
pak::pak("nononoexe/rrstools")Usage
This package provides functions to read and plot RRS map data.
library(rrstools)
# Sample GML file
gml <- system.file("extdata", "map-test.gml", package = "rrstools")
# Read the map data from the GML file
map_data <- read_rrs_map(gml)
# Print the map data
