StructTS
Dear all,
I am applying the StructTS function in ts-package. For some time series
the program terminates and the following error appears:
Error in optim(init[mask], getLike, method = "L-BFGS-B", lower = rep(0,
:
L-BFGS-B needs finite values of fn
Do someone know what do I have to adjust in the original time series to
avoid this error? It works fine for some subsets of the time series
only.
Thank you in advance.

Time Series smoothing
...out. However, I am having some problems
smoothing and plotting the smoothed version.
> A <- as.ts(read.table(choose.files()))
> x <- as.ts(A[,10])
> plot(x)
> > plot(smooth(x))
plot(smooth(x)) looks exactly like plot(x). Also,
> StructTS(x)
Error in optim(init[mask], getLike, method = "L-BFGS-B", lower = rep(0, :
L-BFGS-B needs finite values of 'fn'
The HoltWinters smoothing or the Kalman smoothing don't work either for
various errors... I'm not quite sure what's wrong.
Thanks.

I'll be happy to supply any information I can upon request to help the
developers solve this apparent problem. I've searched the R mailing

Problem in StructTS() when the first element of the serie is NA ( (PR#3990)
...is a NA (R:R1.7.0, os: w2ksp4).
Please look at the following code:
a=rep(1:7,10)
library(ts)
#this works
StructTS(a)
#this works
x=a
x[2]=NA
StructTS(x)
#this doesn't work
x=a
x[1]=NA
StructTS(x)
The last command returns this error
"Error in optim(init[mask], getLike, method = "L-BFGS-B", lower = rep(0, :
L-BFGS-B needs finite values of fn"
