Wow, thank you for all your answers.
You were completely right michael. Well, it's my fault. I didn't understood
your 2nd reply, when you were talking about arguments for larger gaps. I
thought it was for deleting big gaps too. I apologize.
It was too easy in fact. I also didn't noticed the argument "maxgap" of the
function.
Finally, it works perfectly only with this:
require(zoo)
imputation <- function(x){
met <- na.approx(x, maxgap = 4)
return(met)
}
data <- myts[,2:5]
myts[,2:5]<-apply(data,2,imputation)
Sorry for my stupidity. I'll try to be more careful next time, for such
small problems (when I was thinking it would be a big one) ;).
Well, thank you very much michael and the other repliers, and thank you for
having spared a bit of your time for me!
