The server function of the pca module

Source: R/pca.R
pca.Rd

This module calculates a PCA and formats components and loadings for display. It uses a common set of controls, generated with the scatterplotcontrols module, to power scatter plots for both components and loadings produced by the scatterplots module.

Usage

pca(id, eselist)

Arguments

id

Module namespace

eselist

ExploratorySummarizedExperimentList object containing ExploratorySummarizedExperiment objects

Details

This function is called directly, using the same id as its UI counterpart, and wraps its logic in moduleServer() (see example).

Matrix and UI selection elements provided by the selectmatrix module

Examples

data(airway, package = "airway")
ese <- as(airway, "ExploratorySummarizedExperiment")
eselist <- ExploratorySummarizedExperimentList(ese)
#> Creating ExploratorySummarizedExperimentList object

# Almost certainly used via application creation

if (interactive()) {
  pca("pca", eselist)
  app <- prepare_app("pca", eselist)
  shiny::shinyApp(ui = app$ui, server = app$server)
}
