[BioC] Draw histogram with an optional "Weight" column

[Zhu, Lihua (Julie)]

Hi,

Is there a good way to draw histogram with an optional "Weight" column,
perhaps by manipulating the count in the hist output? If  Weight column is
selected, then the value of each cell is incremented by the value of
"Weight" column, otherwise by 1 which is the behavior in hist function.

Thank you very much for your kind help!

Best regards,

Julie
