[R] Adjusted residuals

[Dominik Heinzmann]

Dear users,
Given a equation of the form y=a(1-exp(bt), where a,b parameters and t=age
and given prevalences for t=1,2,3,4,5
What is a nice way to plot a kind of adjusted residuals at those values 
for t?
How should one scale them to account for small counts at some values for t?
Thanks
