Bill,

   Ah, so. I did not look to see if all the data frames that did plot had at
least one value in each column.

   Ugly is only skin deep; I'll take your advice on addressing this issue
with the two streams that fail to plot.

   There is still something I'm not doing properly because a lattice xyplot()
of TDS concentrations by time conditioned by sites on a stream show more
points than do the zoo line plots for the same stream. I assume that's not
correct. I need to look for the reason(s) for the differences, but I must
get a report revised and out to a client today so it will be at least
tomorrow before I'm back on this.

Thanks very much,

Rich
