Hello.

I'm playing with Kalman filter.

library(sspir)
m1 <- SS(y=t(t(sin(1:20)))) # dummy data
plot(m1$y, type="l")
m1.f <- kfilter(m1)
m1.s <- smoother(m1.f)
lines(m1.f$m, lty="dotted",col="blue")
lines(m1.s$m, lty="dotted",col="red")

I was wondering how it's possible to forecast using "sspir" library.
I read the topic "Kalman Filter Forecast using SSPIR", but I have
no a great math basis, so I need an hint to write the forecasting code.

Another great package I explored is "dse".
It seems there is a function to do forecasting, but I am not to be able
to translate my snippet using "dse" library.

Can you help me?

Thanks in advance,
Alberto Santini
