Hi all,

I have a huge dataset of values and I have precalculated outside of R the
frequency/count distribution (as for example counts returned by hist
function or the output of table function). For example,

>x<-hist(c(1,2,2,2,1,3), breaks=0:3, plot=F)
> x
$breaks
[1] 0 1 2 3

$counts
[1] 2 3 1

Is there any function to calculate boxplot based on the counts?

I guess I could "expand" the count vector to a values set and run boxplot
but the problem is that I have a lot of data (300,000^2). Another way could
be to calculate median and quartiles myself and custom draw the boxplot but
seems complicated.

Do you happen to know some more automated way, maybe a function in R?

Many thanks for the help.

Best regards,
Ioannis
