Choose file or directory to open via 'Python'

Choose a directory, one or multiple files to open, or choose a file to save.

Usage

  multiple = FALSE,
  title = ifelse(multiple, "Choose Files", "Choose a File"),
  message = "",
  verbose = FALSE,
  force = FALSE
)

choose_filesave()

choose_directory(
  initialdir = NULL,
  title = "Choose a Directory",
  message = "",
  verbose = FALSE
)

Arguments

initialfile, initialdir: initial selection of file or directory
multiple: whether to open multiple files
title, message: dialogue title and message
verbose: whether to verbose debug information
force: whether to force using 'Python' when native R functions are available, default is false

Value

User-selected paths. If the users select nothing, then NULL

will be returned. For multiple file selection, multiple paths will be returned.

Details

Base-R has file.choose function to choose files. However, users cannot select multiple files nor directories. These functions fill the gap by using 'Python' 'tkinter' package. Please make sure that one-time setup function configure_conda has executed before running these functions.

The functions must run as interactive mode. If you run the functions on a server, most likely you will get nothing. The functions themselves do not check if you are running under interactive sessions. You must check by yourself.

Examples


if(interactive()) {
  choose_fileopen(multiple = TRUE)
}
