Explore model matrix — ExploreModelMatrix • ExploreModelMatrix

Given a sample data table and a design formula, explore the resulting design matrix graphically in an interactive application.

ExploreModelMatrix(
  sampleData = NULL,
  designFormula = NULL,
  addStopButton = TRUE
)

Arguments

sampleData: (optional) A data.frame or DataFrame with sample information. If set to NULL, the user can upload the sample information from a tab-separated text file inside the app, or choose among a collection of example designs provided in the app.
designFormula: (optional) A formula. All components of the terms must be present as columns in sampleData. If set to NULL, the design formula can be specified after launching the app.
addStopButton: Logical scalar. If TRUE (default), will add a button to stop the app (by calling shiny::stopApp).

Value

A Shiny app object

Examples

app <- ExploreModelMatrix(
  sampleData = data.frame(genotype = rep(c("A", "B"), each = 4),
                          treatment = rep(c("treated", "untreated"), 4)),
  designFormula = ~genotype + treatment
)
