Install packages

The following function installs and loads all the packages required for this workshop. While this function only installs packages that aren’t currently installed, it may take several minutes.

load_pkgs <- function(pkgs) {
  inst_pkgs <- pkgs[!pkgs %in% installed.packages()]
  for(p in inst_pkgs) install.packages(p, ask = FALSE)
  sapply(pkgs,require,character=TRUE)
}

pkgs <- c("terra", "rlandfire", "rgbif",
          "dplyr", "predicts", "tidymodels",
          "sf", "ggplot2", "themis", "pROC",
          "ecospat", "ranger", "usethis", 
          "rmarkdown")

load_pkgs(pkgs)

     terra  rlandfire      rgbif      dplyr   predicts tidymodels         sf 
      TRUE       TRUE       TRUE       TRUE       TRUE       TRUE       TRUE 
   ggplot2     themis       pROC    ecospat     ranger    usethis  rmarkdown 
      TRUE       TRUE       TRUE       TRUE       TRUE       TRUE       TRUE 

If you have not previously installed spatial packages in R (e.g., terra) you may encounter an error. The most common issue is a result of not having gdal installed. If you encounter an error, any of the workshop organizers can help you troubleshoot.

Mac

If you are using a Mac and don’t have gdal installed, follow these directions.
