matrixMainServer: Server module server for matrix with drilldown interaction

In avucoh/DIVE: Data Integration and Visual Exploration

Server module server for matrix with drilldown interaction

Description

The matrix responds to reactive plot data and has a linked drilldown component.

Usage

matrixMainServer(
  id,
  mdata,
  colorscales = list(default = list(colorscale_named(pal = "RdBu"), zmin = -1, zmax =
    1), absolute = list(colorscale_heatmap_absolute, zmin = -1, zmax = 1))
)

Arguments

id	Character ID for specifying namespace, see shiny::NS.
mdata	Reactive matrix data from matrixCtrlServer.
colorscales	Optional, a list of custom colorscale functions that takes a numeric matrix and returns either a named colorscale or custom colorscale used for heatmap. If not given, two default colorscale functions are used.

Details

The module handles interactive display of a matrix linked to a scatterplot that accesses underlying data for a user-clicked cell. It works with matrixCtrlServer, which returns the data object. Generally, this module only handles visualization of a matrix while the actual matrix generation can be handled by other modules that feed into it. For the drilldown component that displays underlying data points, the statistical data type (numeric vs. ordinal) matters and may require specifying aesthetic parameters for best representation and consistency across modules.
