## Prerequisites

### Equipment and software requirements

Attendees are expected to use their own computers with a working version of R (version 3.6 or higher) and RStudio (version 1.2 or higher) installed.

R and RStudio are supported by PC, Linux, and Mac OS and can be downloaded for free by following these links
http://www.r-project.org/ and https://www.rstudio.com/products/rstudio/download/#download.

### R packages

Run the code below in R to install all of the required R packages.

```r
install.packages(c("landscapemetrics", "sf", "dplyr", "spData", "usethis", "remotes")
install.packages("spDataLarge", repos = "https://nowosad.github.io/drat/", type = "source")
remotes::install_github("mtennekes/tmaptools", upgrade = TRUE)
remotes::install_github("mtennekes/tmap", upgrade = TRUE)
remotes::install_github("rspatial/raster", upgrade = TRUE)
```

### Check if it works

Afterwards, run the code below (you should see the map as a result):

```{r}
library(tmap)
library(landscapemetrics)
tm_shape(landscape) +
  tm_graticules() +
  tm_raster()
```

Please see https://datacarpentry.org/geospatial-workshop/setup.html for instructions on how to install geospatial library dependencies.
