filterWidget: 'setFilterWidget' sets the filter widget for the current...

In AnalysisPageServer: A framework for sharing interactive data and plots from R through the web

Description

setFilterWidget sets the filter widget for the current analysis. This is the function most commonly used.

getFilterWidget retrieve the filter widget for the current analysis. This is normally used internally, to construct the final response for the analysis.

The AnalysisPageFilterWidget object specifies a "filter widget" to be displayed to the user. This is a grid of colored squares, each of which controls the filtering of a subset of the samples based on the values of a pheno field. This object specifies the dimension of the grid, the colors of the squares, rollovers to appear for each square, and the subset of samples that each square filters.

Usage

setFilterWidget(data.field, color, cells, inactive.color = "gray",
  type = "filter_grid")

getFilterWidget()

new.filter.widget(data.field, color, cells, inactive.color = "gray",
  type = "filter_grid")

Arguments

data.field	Name of table field which should be used for filtering.
color	Named character vector. Names should be values (or possible values) that the data field could take on. Values are string specifying colors. These are passed through directly to javascript so they should be valid colors there, whatever that means.
cells	Character matrix. This gives the layout of the filter grid. The values should all be either taken from names(color) or else be NA values. The NA values will be inactive (no rollover or click listeners).
inactive.color	Color for inactive cells (that are the positions with is.na(cells)). Default: "gray"
type	Filter widget type. The only currently supported type is "filter_grid".

Details

new.filter.widget is the constructor for this object. This should be used when constructing an AnalysisPageReponse explicitly, with the return value then passed to new.datanode.plot.

Value

setFilterWidget returns the newly set AnalysisPageFilterWidget object

getFilterWidget returns the curretn AnalysisPageFilterWidget object, or NULL if it has not yet been set

new.filter.widget returns an AnalysisPageFilterWidget
