[R] Plotting an lme( ) object

[Greg Tarpinian]

Based on the suggestions, the following yielded 
satisfactory results:


plot(FOO.lme4, resid(.,type = "p") ~ fitted(.) | GROUP, 
     id = 0.05, adj = 1, 
     idLabels = paste( round(FOO$VALUE,1), 
                       rep(" ",length(FOO$VALUE)) ),
     main = "Pearson Residuals vs. Fitted Values, by GROUP",
     between = list(x = .5, y = .5))


Using paste() to hardcode an extra "space" provided me with
the necessary graphical offsets.

Regards,

     Greg
