swipe direction corona sdk

Question

I'm new in Corona SDK and I would like some help: I want to check the direction of the user swipe, I have an object:

local Rect = display.newRect(30,30,30,30)
Rect:setFillColor(255,0,0)

and I want to add to him a Listener

Runtime:addEventListener("touch",SwipeTouchEvent)

in the function I want to check if there was a swipe, and for what direction the swipe was. if is was up add 1 to int up; if it was down, add 1 to int down; if it was right add 1 to int right and if it was left, add 1 to int left; and display all the ints on the screen... thanks for helpers!

Here is an article that talks about how to change scenes by swiping left or right. see if you can pull this apart and take what you need.

hint :

local function startDrag(event)
        local swipeLength = math.abs(event.x - event.xStart) 
        print(event.phase, swipeLength)
        local t = event.target
        local phase = event.phase
        if "began" == phase then
            return true
        elseif "moved" == phase then
        elseif "ended" == phase or "cancelled" == phase then
            if event.xStart > event.x and swipeLength > 50 then 
                print("Swiped Left")
            elseif event.xStart < event.x and swipeLength > 50 then 
                print( "Swiped Right" )
            end 
        end
    end
