Mailing list now included (apologies, first time I post anything so not quite sure how it works).
You are quite right, it was a typo. I meant to write that plot.xmean.ordinaly(). So please let me correct my last statement: the plot.xmean.ordinaly() command and plot() command are interchangeable as long as x is an object x of class "xmean.ordinaly", and plot.xmean.ordinaly() is best used if the object is not of class "xmean.ordinaly" or if you are unsure what class it it. Is this a correct encapsulation?
