tkchoose.files | R Documentation |
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.
tkchoose.files(default = "", caption = "Select files", multi = TRUE, filters = getDefaultFilters(), index = nrow(filters))
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. |
A character vector giving zero or more file paths. If user cancels operation, character(0) is returned.
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.
