R help - Jun 2013 - Tolearance Interval calculation for each point in a data set?

Hello,

I am looking for tolerance interval related methodologies and found the 
package "tolerance" which will e.g. nicely calculate the 95%/95%
tolerance
limits of a given regression. What I am looking for, however is not only the 
the tolerance limits this calculation defines, but I would like to know for 
each data point in the set which tolerance band is passing through it.

Does anyone know of such methodology and if yes an R implementation?

Thank you for any pointers.

Sincerely, Joh
