The `Maps`, `Mapdata` and `Oz` packages to get most common boundaries

The maps, mapdata and oz packages provide the boundaries of the most common world regions like the US, Europe, New Zealand and more. This post describes how to use them to avoid struggling finding input data.

# `maps` package {#maps} ***

The [maps](https://cran.r-project.org/web/packages/maps/maps.pdf) package is the best source of geospatial data in R. The whole list of offered data is available typing: `help(package='maps')`. It includes: - World: `world`, `world.cities`, `lakes` - US: states, `county`, `state`, `usa` - France: `france` - Italy: `italy` - New zealand: `nz` The code below shows how to use one of this geospatial object.

```{r thecode, echo=FALSE, out.width = "100%", fig.height=4} # Load library library(maps) # Check all available geospatial objects: # help(package='maps') # Map of the world: map('world',col="grey", fill=TRUE, bg="white", lwd=0.05, mar=rep(0,4),border=0, ylim=c(-80,80) ) ```

```{r thecode, eval=FALSE} ``` # `mapdata` package {#mapdata} ***

The [mapdata](https://cran.r-project.org/web/packages/mapdata/mapdata.pdf) package extends the `maps` package with more geospatial datasets: - `china` - `japan` - Other world versions like pacific Centric (`world2Hires`) See complete list with `help(package='mapdata')`

```{r thecode2, echo=FALSE, out.width = "100%", fig.height=4} # Load library library(mapdata) # Check all available geospatial objects: # help(package='mapdata') # Map of Japan: map('japan',col="black", lwd=1, mar=rep(0,4) ) ```

```{r thecode2, eval=FALSE} ``` # `oz` package {#oz} ***

The [oz](https://github.com/cran/oz) package provides several geospatial object concerning Australia. Plot the general country using the `oz()` function, or states using `nsw()`, `qld()` and so on.. Type `help(package='oz')` for documentation.

```{r thecode3, echo=FALSE, out.width = "100%", fig.height=4} # Load library library(oz) # Check all available geospatial objects: # help(package='oz') # Map of Australia par(mar=rep(0,4)) oz( states=TRUE, col="#69b3a2") ```

```{r thecode3, eval=FALSE} ```

```{r, echo=FALSE} htmltools::includeHTML("htmlChunkRelatedMap.html") ```
