I did not intend to criticize anything.  The original poster said that a 
reviewer asked him to make a plot "using the residuals of the lm() and 
plotting them against a covariate".  This is a bit vague, but sounded 
like an added variable plot to me, so I was simply trying to make the 
original poster aware of the existence of added variable plots and point 
him to some places where he could read more about them.
