I am looking at forecast
package HoltWinters
method code from this link (for code understanding purpose). I couldn't find which "R" source file has this predict
function defined in to look at source code. Can some one please help me on how can trace this function to a specific source code file?
pred <- predict(object,n.ahead=h,prediction.interval=TRUE,level=level[1]/100)
Any help would be appreciated.
It is not exported, but you can find it using the :::
operator:
forecast:::predict.HoltWinters
# function (object, n.ahead = 1, newxreg = NULL, se.fit = TRUE, ...)
# ....
forecast<- HoltWinters(datatimeseries, beta=FALSE, gamma=FALSE)
>forecast:-
Holt-Winters exponential smoothing without trend and without seasonal component.
Call:
HoltWinters(x = datatimeseries, beta = FALSE, gamma = FALSE)
Smoothing parameters:
alpha: 0.02412151
beta : FALSE
gamma: FALSE
Coefficients:
[,1]
a 24.67819
Try this, It works for me...
