Based on the suggestions, the following yielded
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.
