cog_disp_filter(
  display,
  var,
  val,
  desc = "link",
  group = "common",
  default_label = FALSE,
  default_active = FALSE,
  filterable = FALSE,
  sortable = FALSE
)

Arguments

display	A string indicating the name of the display to link to.
var	A string indicating the variable name to filter on.
val	A string indicating the value of the filter.
desc	a description for this cognostic value
group	optional categorization of the cognostic for organizational purposes in the viewer (currently not implemented in the viewer)
default_label	should this cognostic be used as a panel label in the viewer by default?
default_active	should this cognostic be active (available for sort / filter / sample) by default?
filterable	should this cognostic be filterable? Default is `TRUE`. It can be useful to set this to `FALSE` if the cognostic is categorical with many unique values and is only desired to be used as a panel label.
