visualise {NACHO}

Visualise quality-control metrics of a "nacho" object

Description

This function allows to visualise results from load_rcc() or normalise() several quality-control metrics in an interactive shiny application, in which thresholds can be customised and exported.

Usage

visualise(nacho_object)

Arguments

nacho_object

[list] A list object of class "nacho" obtained from load_rcc() or normalise().

Examples

if (interactive()) {
  data(GSE74821)
  # Must be run in an interactive R session!
  visualise(GSE74821)
}

if (interactive()) {
  library(GEOquery)
  library(NACHO)

  # Import data from GEO
  gse <- GEOquery::getGEO(GEO = "GSE74821")
  targets <- Biobase::pData(Biobase::phenoData(gse[[1]]))
  GEOquery::getGEOSuppFiles(GEO = "GSE74821", baseDir = tempdir())
