PACF using R for Time series

nikki92

How do I get all the partial autocovariances using the pacf

x_t = z_t -1.1z_t-1 +.28 Z_t=2 z_t is white noise (0,1)

y=ARMAacf(ma=c(-1.1,.28), lag.max 40, pacf = T)

I am only getting the partial autocovariances 1,1 2,2 3,3 ....
I want to get the other terms too like 2,1 3,2 3,3 ....

How do I get it?
