Visualize associations from a correspondence analysis using moonplots

VizIcon Moonplot.svg

Visualizes associations between categorical variables from a Correspondence Analysis, Principal Components Biplot or Linear Discriminant Analysis output. It is a simpler and easier to interpret alternative to a scatterplot.

Code

var heading_text = "Moonplot";
if (!!form.setObjectInspectorTitle)
    form.setObjectInspectorTitle(heading_text);
else 
    form.setHeading(heading_text);
form.dropBox({name: "inputItem", label: "Output", types: ["R:CorrespondenceAnalysis,LDA,PCAbiplot"],
              prompt: "Output of Correspondence Analysis, Principal Components Analysis Biplot or Linear Discriminant Analysis"});
library(flipDimensionReduction)
moonplot <- QInputs(inputItem)
moonplot$output <- "Moonplot"
viz <- moonplot
