Choose a directory interactively using rJava

Share:

Description

Provides the same functionality as choose.dir from utils package, but relies on Java and rJava package and therefore is system independent provided Java 1.5 and higher is installed.

Usage

1

3
  jchoose.dir(default = getwd(),
    caption = "Select Directory",
    modal = canUseJavaModal())

Arguments

default

Which filename or directory to show initially. Default is current work directory.

caption

The caption on the file selection dialog

modal

Indicates how the modality of the dialog is implemented. If TRUE, the modal dialog is used and if FALSE, R repeatedly checks for dialog status (active or not). The latter is used to refresh R Gui window on Windows. Default is canUseJavaModal().

Value

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

Note

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