[R] Need confirmation of my lme() structure

I'm a new user of R and I would need somebody to confirm (or not!) that I'm doing right. I'm analyzing diving characteristics (maximal depth, etc...) of birds breeding in 2 sites, during 2 stages (see data structiring below).

M04 :402 C: 471 Guard:1557

M13    :344   M:2143   Incub:1057                                     M10 
  :252                                  M14    :209                       
          M15    :190                                  (Other):955

I want to analyse the effects of site and stage using REML analyses with site and stage as fixed factors and file (i.e. individual bird) as a random factor.
In R, I would write the following command:

> reml_depthmax <- lme(DEPTHMAX~SITE*STAGE, random=~1|FILE,

Am I right???

Many thanks for your help,
