Hi everybody.

I'm using BFAST program and I have some data to be analized (named
"META.csv" for example).  When I call BFAST in the following way:

meta <- read.csv("C:/META.csv")
meta.ts<-ts(meta, frequency=12, start = c(2005,9))

dis<-frequency(meta.ts) / length(meta.ts)

meta.sc<-bfast(meta.ts, h=dis, max.iter=1)
meta.sc$output

The last statement has the option of write it in the next fashion:

meta.sc$output[[1]]

or

meta.sc$output[[2]]

which have associated

meta.sc$output[[1]]$bp.Vt    or
meta.sc$output[[2]]$bp.Vt

respectively...However I really don't understand what's the difference (if
such exists) in choosing [[1]] or [[2]]

I've noticed that they show different results but I don't understan which is
"correct" or "wrong" and when to choose any of them.

thanks a lot for your unvaluable help.

Regards
