Why do you need to use letters? AFAIK this was only illustration what
could be root of the error message. If the function requires ordered
factor you can use
your.ordered.factor <- ordered(your.unordered.factor)
I do not remember original mail but to get rid of error message, the
function probably needs as an input ordered factor or numeric values. You
shall consult help page for this function which option is valid.
