[R] How to set initial values in lme ?

[Hoai Thu Thai]

Hello R-users,

Does anyone know how to set initial values in lme? I have a problem of 
non convergence and would like to try different inital values.
Is lmeScale the right function to do it and how many parameters do we 
need to specify, only fixed parameters or also random effects ?

Thanks for any advice,

Best regards,
