[R-SIG-Finance] [R-sig-finance] Problem on ploting of a zoo object

Let say I have following codes

dat <- rnorm(100)
date1 <- 35886
dat2 <- zooreg(dat, as.Date(date1, origin="1900-01-01"), frequency=12)
index(dat2) <- format(index(dat2), "%m/%y")

However when I try to plot "dat2", I got following error :

> plot(dat2)
Error in plot.window(...) : need finite 'xlim' values
In addition: Warning messages:
1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion
2: In min(x) : no non-missing arguments to min; returning Inf
3: In max(x) : no non-missing arguments to max; returning -Inf

Can anyone please tell me how to get the plot?
