Dear List The UKgas data is stored as an object of class 'ts'. I am trying to use "UKgas" in a formula as argument to a function. However, I do not know how to access the 'time series' information in the response (such as start() end() etc.). Here is a boiled down example. ssm <- fu...

In the examples for StructTS -- ($RHOME)/library/stats/man/StructTS.Rd -- could par(mfrow = c(4, 1)) plot(log10(UKgas)) plot(cbind(fitted(fit), resids=resid(fit)), main = "UK gas consumption") become plot(log10(UKgas)) par(mfrow = c(4, 1)) plot(cbind(fitted(fit), resids=resid(fit)), main = "UK gas consumption") ## Note that par was moved down This makes the plot of UKgas use the whole plot...

...varies the other variances to find the maximum likelihood estimates. If I am right, I suggest the docs changed to: "If supplied, only \code{NA} entries in \code{fixed} will be varied." ("non-" has been deleted). E.g. try the following after invoking R: R> StructTS(log10(UKgas), type = "BSM", fixed=c(0,NA,NA,NA)) Observe, that the first variance is fixed to zero, while the remaining three are varied to obtain the maximum likelihood estimates. 2) There is a minor typo in the explanation of 'fitted' - a parenthesis is missing. I suggest changing "...
