R help - May 2004 - Nonlinear robust regression

Hello,
 I would like to make a nonlinar fit (exactly the exponencial fit)
 to the data. But my data set is not
 ideal at all, so any robust method (such as LTS) would be bettre then
 LS. Could you advice me, please, if there is any R package or R function 
 which provides the nonlinear robust regression? 
 Thank you 
 Eva Gelnarova

The package nlrq does nonlinear l1 regression.  This isn't robust in the
design directions, but is in the response direction.
