Many thanks to Bill Venables and Douglas Bates who responded almost immediately
to my question.
Professor Venables pointed out that I left out an equal sign.
I entered:
Monk.fit1<-lme(fixed=GLOBULIN~AGE,
+ data=Monkey,random~AGE|ID)
and received the following message:
Error in lme.formula(fixed = GLOBULIN ..: Length of vari
able 1 is 4 != length of row names (1765)
I should have entered an equal sign after random, i.e. random=~AGE|ID).
The full, and correct command would thus have been:
> Monk.fit1<-lme(fixed=GLOBULIN~AGE,
+ data=Monkey,random=~AGE|ID)
Again, I thank Professors Venables and Bates.
