R help - Mar 2006 - Having trouble with tsdiag function on a time series

Hello,

I'm getting the following error message when I try to run 'tsdiag'
on what seems to be a valid time series:
> tsdiag(small)
returns:

[Error in tsdiag(small) : no applicable method for "tsdiag"]

where small is a little test series where I have isolated this problem (the
original has 30-years worth of daily data)

When I print it (small), it looks like the following:

Time Series:
Start = c(1990, 1) 
End = c(1990, 31) 
Frequency = 365 
[1]  0.0 16.0 10.0  0.0  0.0  0.0  0.0  0.0  2.0  2.2  0.0  0.0  0.0  0.0  0.0 
0.0  0.0  2.5  0.1
[20]  2.4  0.0  0.0  0.0  0.0  9.6  0.0  0.0  0.0  0.0 25.2  7.0

I've found some postings in the r-bugs list which suggest that "no
applicable method" can stem from a conflict across namespaces. I've
tried qualifying the call:
> stats::tsdiag(small)
with the same result.

Many thanks in advance for any help.

tsdiag is for diagnostic plots from time-series fits, not time series.
