In csoneson/iSEE: Interactive SummarizedExperiment Explorer

Create observers for a modal for custom dimnames

Description

Create observers to launch a modal where users can input a list of custom row or column names. These observers register input changes in the app's memory and request an update to the affected panel.

Usage

.createCustomDimnamesModalObservers(
  plot_name,
  slot_name,
  button_name,
  se,
  input,
  session,
  pObjects,
  rObjects,
  source_type
)

Arguments

plot_name	String containing the name of the current panel.
slot_name	String specifying the slot of containing the names of the custom features. This will be modified by user interactions with the modal.
button_name	String containing the name of the button in the panel UI that launches the modal.
se	A SummarizedExperiment object after running .cacheCommonInfo.
input	The Shiny input object from the server function.
session	The Shiny session object from the server function.
pObjects	An environment containing global parameters generated in the iSEE app.
rObjects	A reactive list of values generated in the iSEE app.
source_type	String specifying the type of the panel that is source of the selection, either "row" or "column".

Details

This should be called in .createObservers for the target panel. It assumes that a button element with the suffix button_name is available in the UI (i.e., the full name is created by concatenated plot_name with button_name).

The modal UI provides options to sort the dimnames, validate them, clear the current text and import a selection from a specified row transmitter. These are all transient until “Apply” is clicked, at which point the app's memory is modified and an update is requested.

The custom names are stored in the slot_name as a single string with names separated by newlines. Hashes are treated as comments and any content after a hash is ignored when interpreting the names. Any leading and trailing whitespace is also ignored during interpretation.

Value

Observers are set up to launch the modal and monitor its UI elements. A NULL is invisibly returned.
