Get a module’s path
The following functions retrieve information about the path of the directory that a module or script is running in.
path(mod) base_path(mod) script_path() knitr_path() shiny_path() testthat_path()
mod |
a module environment or namespace. |
script_path takes a best guess at a script’s path, since R does not
provide a sure-fire way for determining the path of the currently executing
code. The following calling situations are covered:
Path explicitly set via set_script_path
Path of a running document/application (knitr, Shiny)
Path of unit test cases (testthat)
Path of the currently opened source code file in RStudio
Code invoked as Rscript script.r
Code invoked as R CMD BATCH script.r
Script run interactively (use getwd())
path returns a character string containing the module’s full
path.
base_path returns a character string containing the module’s
base directory, or the current working directory if not invoked on a module.
script_path returns a character string that contains the
directory in which the calling R code is run. See ‘Details’.
knitr_path returns the directory in which the currently knit
document is run, or NULL if not called from within a knitr
document.
shiny_path returns the directory in which a Shiny
application is running, or NULL if not called from within a
Shiny application.
testthat_path returns the directory in which testthat
code is being executed, or NULL if not called from within a
testthat test case.
