processMultiSelections: Process multiple selections

In csoneson/iSEE: Interactive SummarizedExperiment Explorer

Process multiple selections

Description

Generate and execute commands to process multiple selections, creating variables in the evaluation environment with the identity of the selected rows or columns.

Usage

.processMultiSelections(x, all_memory, all_contents, envir)

Arguments

x	An instance of a Panel class.
all_memory	A named list of Panel instances containing parameters for the current app state.
all_contents	A named list of arbitrary contents with one entry per panel.
envir	The evaluation environment. This is assumed to already contain se, the SummarizedExperiment object for the current dataset.

Details

This function is primarily intended for use by developers of new panels. It should be called inside .generateOutput to easily process row/column multiple selections. Developers can check whether row_selected or col_selected exists in envir to determine whether any row or column selection was performed (and adjust the behavior of .generateOutput accordingly).

Value

envir is populated with one, none or both of col_selected and/or row_selected, depending on whether x is receiving a multiple selection on the rows and/or columns. The return value is the character vector of commands required to construct those variables.
