ok, not sure if this is related to this mandatory R packages

ok, do you have ggplot2 installed? If not, try to import the attached
script (copy and paste the content in the editor) and try to use it
if it works and you did not had ggplot2 installed then Processing is
able to install additional packages, if not, then I'm totally wrong :)
