Description Chris Sims 2012-05-20 03:05:01 UTC
window.ts()<-  fails with an error message "too many replacement values supplied" when the argument and replacement value are multiple time series objects, even though it works properly if single-series columns of the same objects are selected.  

My R version is svn revision 58871, 64-bit linux, 2012-3-30.

Code to reproduce:

a <- ts(matrix(1:36, 12), start=2000, freq=12)
b <- ts(matrix(1:48, 16), start=c(1999,9), freq=12)
window(a, start=c(2000,6)) <- window(b, start=c(2000,6), end=c(2000,12)) 
## line above generates error message
window(a[,2], start=c(2000,6)) <- window(b[,3], start=c(2000,6), end=c(2000,12))

In fact only the error message is wrong: the code later works.

Fixed for 2.15.0 patched (and please if you are going to report on R-patched, do it on a current version).
