Dear R-Users,
   
  Is it possible to get the covariance matrix from an lme model that did not converge ? 
   
  I am doing a simulation which entails fitting linear mixed models, using a "for loop". 
  Within each loop, i generate a new data set and analyze it using a mixed model.  The loop stops When the "lme function" does not converge for a simulated dataset. I want to inquire if there is a method to suppress the error message from the lme function, or better still, a way of going about this issue of the loop ending once the lme function does not converge.
   
  Thanks in advance,
  Pryseley
