Server function for scatterplotcontrols module

This module provides controls (2D/3D, axes etc) for scatter plots, which may then be used by one or more instances of the scatterplot module.

Usage

scatterplotcontrols(
  id,
  getDatamatrix,
  x = NA,
  y = NA,
  z = NA,
  makeColors = NULL
)

Arguments

id

Module namespace

getDatamatrix

Reactive expression that returns a matrix from which coulumn headers will be used to create axis select drop-downs. The same reactive should be supplied to the scatterplot module

x

A value supplied for this parameter will cause a hidden field to be generated instead of a select, useful for scatter plots that don't need the user to select axes (default: NA)

y

A value supplied for this parameter will cause a hidden field to be generated instead of a select, useful for scatter plots that don't need the user to select axes (default: NA)

z

A value supplied for this parameter will cause a hidden field to be generated instead of a select, useful for scatter plots that don't need the user to select axes (default: NA)

makeColors

Boolean: use controls for coloring?

Value

output A list of reactives for accessing input values

Examples

scatterplotcontrols_reactives <- scatterplotcontrols("pca", pcaMatrix, x = 1, y = 2) # To have fixed axes rather than user-selected
#> Error in scatterplotcontrols("pca", pcaMatrix, x = 1, y = 2): could not find function "scatterplotcontrols"
