quadratic trends and changes in slopes
...nce of a quadratic trend was in
the N=1-5 range (t(9) = 7.33, p< .001 for the control group, and t(5) =
5.35, p = .005 for the Turner group). This indicates a subitizing range
of 4 for both groups. This divergence from a linear increase in RT
suggests the deployment of a new process for the last numerosity added."

histogram with mean for every break
Dear R-users,
I need to produce a histogram where for every breaks there are the mean of the data.
I tried tu use the function >hist(x, break=20 ... ) but this return the numerosity for every breaks, not the mean.
Any hint?
Thanks in advance,
francesco

2) please provide reproducible examples.
As example(pooltest) keeps working fine, as do some other cases I tried
(Grunfeld data etc.), I don't know what the problem is but evidently
your data are peculiar in exposing it.
Sure the data numerosity must be enough, but maybe you have something
which doesn't vary along some dimension, and gets dropped? or some
groups which are all-NA? Do the "random" and "pooling" options crash as
well?
You might use traceback() to better identify the problem, and/or send a
complete exa...
