Arguments

id

(string) the shiny module id.

assays

(reactive character)
available assays in the currently selected experiment.

exclude_assays

(character)
names of the assays which should not be included in choices in the teal module.

Value

The chosen assay as a reactive string.

    encoding = uiOutput(ns("encoding_ui")),
