[R] Some questions

[Savano Pereira]

Hello people,

I'd like to ask you some questions:

1-How can I introduce an intercept in arima.sim function?

2-How can I edit the initial values (=initial conditions) in arima.sim function?


3- How can I put my own x-axis in plot function?
Ex: It could be a vector or array with same dimension of the plotted variable.


4-How can I augment grid values on y-axis or x-axis in plot function?
Ex:Imagine that the gave grid is 10 by 10 and I would like the put it in 2 by
2 or 5 by 5.

5- Is it possible to introduce or to construct some kind of kernel on spectrum
function?
Ex: Parzen, Bartlet, etc..

Waiting for answers.
