Init nnetTs (or nnet?) with a former Neural Net
I am new to R and use nnetTs - calls.
If a time series of let's say 80000 Datapoints and did call nnetTs I want
make a new net
for the old ponts plus the next 1000 points (81000 datapoints total) what
would again
cost much calculation time.
So I want to pre-init the new net with the former wonnen net to reduce the

como hacer grafico de un modelo setar
...t <- window(x, start = 1925)
mod.test[["linear"]] <- linear(x.train, m = 2)
mod.test[["setar"]] <- setar(x.train, m = 2, thDelay = 1)
mod.test[["setarc"]] <- setar(x.train, m = 2, thDelay = 1,
include=c("none"))
mod.test[["nnet"]] <- nnetTs(x.train, m = 2, size = 3, control =
list(maxit = 1e+05))
mod.test[["aar"]] <- aar(x.train, m = 2)
#ahora la predicción:
frc.test <- lapply(mod.test, predict, n.ahead = 10)
#Dibujamos en una misma gráfica todas las predicciones que hemos
calculado para los modelos estimados:

Neural Net forecasting
Are there any packages in R that are suitable for doing time series
forecasting using neural networks? I have looked in the nnet package and
neural package and they both seem geared towards classification.
thanks,
Spencer
