tkchoose.files {rChoiceDialogs}

Choose a list of files interactively using tcltk

Description

Provides the same functionality as choose.files from utils package for Windows, but relies on tcltk package and therefore is system independent provided tcltk is installed.

Usage

  tkchoose.files(default = "", caption = "Select files",
    multi = TRUE, filters = getDefaultFilters(),
    index = nrow(filters))

Arguments

default

Which filename to show initially

caption

The caption on the file selection dialog

multi

Whether to allow multiple files to be selected

filters

A matrix of filename filters. If NULL, all files are shown. Default is filters=getDefaultFilters().

index

Which row of filters to use by default.

Value

A character vector giving zero or more file paths. If user cancels operation, character(0) is returned.

Note

tkchoose.files() is called internally by rchoose.files() if it's appropriate for a given platform/graphics combination. Calling tkchoose.files() directly forces the package to use tcl tk based dialog regardless of system capabilities and therefore may fail. Use the direct call to tkchoose.files() only if it seems beneficial to bypass the rchoose.files() decision logic.
