Dear R Users,
A recent update on base packages on my R installation has introduced a
problem to my code which did not exist before the update. The offending
function is rbind, which fails where it was working just fine before the
update.
I have two zoo objects, foo and bar, indexed by class Date. foo starts
from "2007-10-09" and bar from "2007-10-10". I attempt to pad bar with a
zero on Date "2007-10-09".
> foo<-zoo(1,order.by=as.Date("2007-10-09"))
> bar<-zoo(2,order.by=as.Date("2007-10-10"))
> bar <- rbind(zoo(0, order.by = index(foo)[1]), bar)
Error in rep.int("", nrow(r)) : incorrect type for second argument
>
Weird. I am certain the problem is due to a recent update to this package
as I have an R installation on two pcs, the same line of code works well
on one and not on the other.
Any help/pointers appreciated ? Is this perhaps a bug in rbind ? I am on R
version 2.7.2, Windows XP SP2.
Thanks in advance,
Tolga
