Hello! I have two questions.
First of all, I have a problem dealing with acf
(Autocovariance function) and need help. First I
defined a time series, x, which is a vector created by
x <- ts(rnorm(200)). So I plugged the series directly
into the acf function, acf(x) and an error message
popped up as:
Error in .C("acf", as.double(x), as.integer(sampleT),
as.integer(nser), : C/Fortran function name not in
load table
I downloaded R to my PC and am thinking if it's
anything to do with the operating system. Please help
me out!
The second question is about arima simulation. I have
an AR and MA process and need to simulate 200
observations from these two models. Don't know how to
do.
Thank you for the help! You can send me a mail at
lamkel at yahoo.com.
Regards,
Kelvin Lam
