R help - Mar 2012 - Extracting data from a zoo by date

Dear all,

I know that it is a silly question, but I have a zoo object like this:       
   
                    valor1  valor2         
01/02/08 36.7381 17.0097 
01/03/08 36.9296 16.8331
01/04/08 35.6934 16.3539 
01/07/08 35.3539 16.3791 
01/08/08 36.3811 16.9340 
01/09/08 37.9220 17.6655 

The name is nuevo.zoo and I need to extract the data for a giving day, for
example for 01/03/08 and for the first column (36.9296). How can I do that?

Sorry but I was looking for on the Internet, and I did not find the answer.
I'm very new to the world of R project.

Thanks a lot.

dt <- as.Date("01/03/08", "%m/%d/%y")

nuevo.zoo[dt]
# or
window(nuevo.zoo, dt)

See ?window.zoo
