Changing defaults
_________________

Default chunk options are stored in `pweave.rcParams["chunk"]["defaultoptions"]`
dictionary. You can manipulate the dictionary to change the options.

**Have a look at current defaults:**

<<>>=
import pweave
import pprint
pprint.pprint(pweave.rcParams["chunk"])
@

**Change wrapping off and default figure position to "h!"**

<<>>=
pweave.rcParams["chunk"]["defaultoptions"].update({'wrap' : False, 'f_pos' : "h!"})
#Updated options
pprint.pprint(pweave.rcParams["chunk"])
@
