Assignment in for loops

["W. Bauer" <bauerwo@gmx.net>]

Dear all

I have a couple of large time series stored in a directory called "liqts". I would like to perform calculations on several of these time series. Normally, the following works without problem:

obj.list<-c("serA","serB")

for (obj.ind in 1:length(obj.list)){

      series<-get(obj.list[obj.ind],where="liqts")

      day.av<-aggregateSeries(series,by="days",FUN=mean)

}

But suddenly, I get the error messages

  1: Object "series" not found in frame 1 for permanent assignment (maybe assigned a `for'

   loop variable?)

  2: Object "obj.list" not found in frame 1 for permanent assignment (maybe assigned a

   `for' loop variable?)

What went wrong? Many thanks for advice,

W. Bauer
