set.wd

Set working directory to where the current file is.

Description

Set working directory to the path of the currently opened file. You can use this function in both .R/.Rmd files and the R console. RStudio (version >= 1.2) is required for running this function.

Usage

set.wd(path = NULL, directly = TRUE, ask = FALSE)

Arguments

`path`	`NULL` (default) or a specific path. Default is to extract the path of the currently opened file (usually .R or .Rmd) using the `rstudioapi::getSourceEditorContext` function.
`directly`	`TRUE` (default) or `FALSE`. Default is to directly execute `setwd("...")` within the function (recommended). Otherwise, it will send code `setwd("...")` to the R console and then execute it (not recommended due to a delay of execution).
`ask`	`TRUE` or `FALSE` (default). If `TRUE`, you can select a folder with the prompt of a dialog.

Value

Invisibly return the path.
