geouy is an R package that allows users to easily access official spatial data sets of Uruguay. The package includes a wide range of geospatial datasets as simple features (sf), available at various geographic scales and for various years with harmonized attributes and projection (see detailed list below).
# From CRAN
install.packages("geouy")
library(geouy)
# Use the development version with latest features
utils::remove.packages('geouy')
devtools::install_github("RichDeto/geouy")
library(geouy)
obs. If you use Linux, you need to install a couple dependencies before installing the libraries sf and geouy. More info here.
The syntax of all geouy functions operate one the same logic so it becomes intuitive to download any data set using a single line of code. Like this:
secc <- load_geouy("Secciones")
Please write the code to obtain the geometries of "Peajes" in a object peaje
You get an sf object of one or more administrative units in Uruguay, according to a query by code or name in the layer.
This function allows you to add a geom variable with a code variable of "zona", "barrio", "localidad", "segmentos", "secciones" or "departamentos".
Allows geocoding directions using IDE_uy.
Plot a variable of your sf object with north and scale, set on a simple theme.
Here's an exercise where the chunk is pre-evaulated via the exercise.eval option (so the user can see the default output we'd like them to customize). We also add a "hint" to the correct solution via the chunk immediate below labeled print-limit-hint.
Modify the following code to limit the number of rows printed to 5:
mtcars
head(mtcars)
You can include any number of single or multiple choice questions as a quiz. Use the question function to define a question and the quiz function for grouping multiple questions together.
