R help - Apr 2015 - Aggregating daily rainfall raster data to bimontly ( twice a month) data

Dear community,

I have daily rainfall raster data for 30 years (1982_2011). I would like to
aggregate daily to bimonthly (twice a month) raster data. Could somebody
kindly help on how to go about it!

Thanks for your help

JOHN


Thanks Kane, bimonthly here means twice a month.
