Quick note about directories with base R.
Check if a directory exists
We use the dir.exists() function. dir.exists() takes as input, a path to a directory, specified as a character string. You can also specify multiple paths in a single character vector. The function will return a boolean indicating if the directory exists.
dir.exists("path/to/dir")
# can specific multiple paths
dir_paths <- c("path/to/dir1", "path/to/dir2")
dir.exists(dir_paths)Create a directory.
We use the dir.create() function. dir.create() takes as input, a path to a direcotyr specified as a character string. We cannot supply multiple character vectors to dir.create().
# create a new directory in the current directory
dir.create("new_dir")
# create a new sub-directory in the new_dir
dir.create("new_dir/sub_dir")
# doesnt' work
dir.create(c("new-dir1", "new-dir2"))
