[R] Time series indexes

[Fernando Saldanha]

I tried to assign values to specific elements of a time series and got
in trouble. The code below should be almost self-explanatory. I wanted
to assign 0 to the first element of x, but instead I assigned  zero to
the second element of x, which is not what I wanted. Is there a
function that will allow me to do this without going into index
arithmetic (which would be prone to errors)?

> x<- ts(c(1,2,3,4), start = 2)
> x
Time Series:
Start = 2 
End = 5 
Frequency = 1 
[1] 1 2 3 4
> x[2] <- 0
> x
Time Series:
Start = 2 
End = 5 
Frequency = 1 
[1] 1 0 3 4
