In rpymat: Easy to Configure an Isolated 'Python' Environment

Choose file or directory to open via 'Python'

Description

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

Usage

choose_fileopen(
  initialfile = NULL,
  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

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.

Value

User-selected paths. If the users select nothing, then NULL will be returned. For multiple file selection, multiple paths will be returned.

Examples

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