Dear All,
I found the following under R 2.3.0 on WINXP (tested on 2 PCs, I do
not have access to the to Linux from this PC, sorry ... )
> set.seed(10)
> x <- ts(rnorm(6),frequency=7)
> x
Time Series:
Start = c(1, 1)
End = c(1, 6)
Frequency = 7
[1] 0.01874617 -0.18425254 -1.37133055 -0.59916772 0.29454513 0.38979430
> x[24] <- NA
> x
Time Series:
Start = c(1, 1)
End = c(1, 6)
Frequency = 7
[1] 0.01874617 -0.18425254 -1.37133055 -0.59916772 0.29454513
0.38979430 NA NA NA NA NA
[12] NA NA NA NA NA
NA NA NA NA NA NA

In addition: Warning message:

Is this behaviour expected for frequencies 12 and 4?
Thank you
