I'm trying to use R's uniroot function from within python. The first arg is a
function, but I'm having trouble creating a function inside python using
r.function().
For example, a naive attempt:
>>> r.function( "x", "x+1" )
Traceback (most recent call last):
File "", line 1, in

Hi Javier,
You should be able to do this yourself. At the end of every email
sent via the list is a URL,
is there something i can do to prevent the following script from leaking memory?

Hello,
Hate to bother you but do you think I could de-register from this list?
Thanks

I does look like the python function garch given in the example is
mixing up few things,
and that var_r in by definition in that very function not a data.frame.

PS: Isnt't "fGarch" for teaching computational finance ?

I do not know garchfit, but it looks to me like it is expecting data
to be a data frame, and you are setting a vector. since you are
setting both variable in the global evironment, wouldn't it work
without the data argument?

Hello,
I am trying to make the following code work.
import rpy2.robjects as robjects
r = robjects.r
r.library("fGarch")
def garch(p, q):
robjects.globalEnv["var_r"] =
robjects.FloatVector([4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,
