Functions constuct a widget to explore BioC's data packages

Description

These functions construct a widget that allow users to visually explore a data package of Bioconductor and read selected elements to R

Usage

DPExplorer(pkgName = "", title = "BioC Data Package Explorer", getFocus
= TRUE)
getTopLevel(title)
loadDataPkg(pkgName)

Arguments

Details

If pkgName is not provided when DPExplorer is called, an entry box is available for users to put a pkgName in later. In either cases, the data package specified by pkgName should have been loaded.

getTopLevel creates a top level window for the widget.

loadDataPkg filters out valid environment objects from a data package.

Value

If only one key is selected, DPExplorer returns a vector of one to more elements. If more than one key is selected, loadDataPkg returns a list of vectors.

getTopLevel returns a tkwin object for the top level window.

loadDataPkg returns a vector of character strings for available data environments.
