R help - Jan 2004 - Help with acf

I would like to get the result of acf min of lag 2 and max of lag 50. 
 When I use time series  ( acf,  lag.max = 50, type="covariance"),  I 
got lag 0 to lag 50.  How do I get lag 2 to lag 50?

Sincerely,

Stephen

Subset the answer in the standard way, as in:

data(Nile)
acf(Nile, lag.max = 50, type="covariance", plot=F)$acf[3:51,,]
