R help - Aug 2007 - variance

hello,
I wanna calculate some variances for the bartlett test and I used the var()
function but I think it isn't a good estimation for the variance I don't
understand why.
In fact when I calculate the variances by myself I don't find the same
results.
Do you know some details about this?
Thanks.

And why do you think that your variance calculation is better than the one 
used in R?
