Subject: [R] a confidence interval from an ANOVA model
To: R help <r-help at stat.math.ethz.ch>


Dear R People:
I have a data set with trt and resp:
trt resp
A 23
A 28
A 37
A 30
B 37
B 44
B 31
B 35
C 42
C 47
C 52
C 38

And I did read.table, constructed an aov object and ran the summary on
the aov object.  I also ran the TukeyHSD function.  All is well so
far.
My question is:  is there a way to put together a confidence interval
from the aov object on a particular mean, please?  It seems like there
should be.

Thanks,
Have a great night/day,
Sincerely,
Erin
