R help - Aug 2013 - Calculation with Times Series

HI,
May be this helps:

?ts1<- ts(1:20)
?ts2<- ts(1:25)
ts1[-(1:3)]<- ts1[-(1:3)]+ts2[1:17]

?as.numeric(ts1)
# [1]? 1? 2? 3? 5? 7? 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37


A.K.


Hey everyone, 

I`m an absolut beginner in R and need some help for an exercise: 

I want to do ordinary calculations with 2 time series. The issue
 with this, that I want to use different elements of time series. 
Let me give you an example: 

I want to sum let`s say the 10th element of time series 1 with 
the 7th element of time series 2. ?And 9th element of TS 1 with 6th 
element of TS 2 and 8th element of TS 1 with 5th element of TS 2 ... 

This pattern of the summation should go all over the time series. 

Is there a function, which allows me to do this, if possible a 
function in which I can change the difference of the position with a 
variable. 

Thanks a lot for your support. I?m for any advice thankful!

Thanks a lot!

It works like I want to!
