In pinin4fjords/shinyngs: Shiny apps for NGS data

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(input, output, session, eselist)

Arguments

input	Input object
output	Output object
session	Session object
eselist	ExploratorySummarizedExperimentList object containing ExploratorySummarizedExperiment objects

Details

This function is not called directly, but rather via callModule() (see example).

Matrix and UI selection elements provided by the selectmatrix module

Examples

callModule(pca, "pca", eselist)

# Almost certainly used via application creation

data(zhangneurons)
app <- prepareApp("pca", zhangneurons)
shiny::shinyApp(ui = app$ui, server = app$server)
