Analog read 12 bits

Hi,
it looks like the analogRead function reads only a 10bits value (0-1023)
is there any way to read an analog value with the 12-bits resolution offered by this chip??
thanks
carlo

analogReadResolution(12); solved the problem

sorry for the silly question

Remember. Going from 10-bits to 12-bits increasingly make the low-order bits more sensitive to noise on analog inputs and analog reference. You may need to implement better electronic hardware designs.

yes, i'm just facing this challenge..
Thanks
