[R] Multistep forecasting with neural networks

HI! Would anybody suggest what function/package/method can I use to obtain forecasts for horizons longer than 1 period ahead? I want to do multistep forecasts with multilayer feedforward networks. I have tried several packages, but it turned out that the functions yield only one-step forecasts.

[R] graph lines don;t appear

Hi I am trying to plot two simple graphs with a grid in background. The axis and grid appears in correct position, but the actual data are not there Can somebody provide me a hint what is missing? The code is: pln <- read.table(file="PLN.txt", header=TRUE, dec=",") par(mfrow=c(1,2)) plot(

[R] neural networks with RSNNS

Hello All! I am training to train a NN with function train() after splitting data with the function splitForTrainingAndTest(). The split is ok (checked it), but when I get a try on training I get this message: Error in UseMethod("train") : no applicable method for 'train' applied to an object

[R] forecasting with L-STAR

Is it possible to make forecasts with L-STAR model (or alternatively E-STAR) ? Although function for LSTAR exists I did not find an indication of forecasting possibilities in the documentation. [[alternative HTML version deleted]] __ R-help@r-pr

[R] time series' year not recognized

I am working with time series and I have encountered a problem with R not recognizing a series properly. I can do the tests and fitting, but when I want to decompose the series I got a message: d<-decompose(data) Error in decompose(dane) : time series has no or less than 2 periods Maybe I have ma
