error deploying Shiny app- develpment package ?

Hi there,I am having trouble deploying my Shiny App.
My app was working fine, and I had published it. Then I changed my stats calculations and decided to use the development version of a package (ALDEX2).

Now I"m thinking how does Shinyapps.io load all the packages called in the library call ?
Is this my problem? Should I save the package file in my shiny directory, but then do I have to have an install function in the script ?

My error message is below.
Any help appreciated. Thanks
