These are all great examples of how you clear a standard canvas, but if you are using paperjs, then this will work:

Define a global variable in JavaScript:

var clearCanvas = false;

From your PaperScript define:

function onFrame(event){
    if(clearCanvas && project.activeLayer.hasChildren()){
        project.activeLayer.removeChildren();
        clearCanvas = false;
    }
}

Now wherever you set clearCanvas to true, it will clear all the items from the screen.
