f_setwd: Set Working Directory Based on Current File or Specified Path

Description

A wrapper around setwd() that sets the working directory to the location of the currently open file in 'RStudio' if no path is provided. If a path is specified, it sets the working directory to that path instead.

Usage

f_setwd(path = NULL)

Value

None. The function is called for its side effects of changing the working directory.

Arguments

path

A character string specifying the desired working directory. If NULL (default), the function sets the working directory to the location of the currently open and saved file in 'RStudio'.

Details

If path is not provided (NULL), this function uses the this.path package to determine the location of the currently open file and sets that as the working directory. The file must be saved for this to work properly.

If a valid path is provided, it directly sets the working directory to that path.

Examples

# NOTE: The use of "if(interactive())" prevents this example from running
# during automated CRAN checks. This is necessary because the example
# requires to be run from an R script. You don't need to use
# "if(interactive())" in your own scripts.
if(interactive()) {
# Store the current working directory, so we can reset it after the example.
current_wd <-  getwd()
print(current_wd)

# Run this commando from a saved R script file, or R Notebook to set the working
# directory to scripts' file location
f_setwd()

# Restore your current working directory
f_setwd(current_wd)
