The major problem is all the padding and the LF in the level names.
This repair is based on the ?gsub example on "## trim trailing white space".

Thanks. I thought of removing white space (didn't notice the spurious
newline) in emacs but did not see that it made a difference. Now I know it
does I'll clean up all the files.
I switched the key to "lines" to match the graph.
OK.
You need to control the color choice differently when using a key.
It is discussed in ?xyplot in the paragraph
Note that 'simpleKey' uses the default settings (see
'trellis.par.get') to determine the graphical parameters in
the key, so the resulting legend will be meaningful only if
the same settings are used in the plot as well. The
'par.settings' argument may be useful to temporarily modify
the default settings for this purpose.
I'll carefully read it.
xyplot(pct ~ sampdate, data = bdf, groups = func_feed_grp, type = 'l',
key = simpleKey(text = levels(bdf$func_feed_grp), space ='right',
points=FALSE, lines=TRUE),
par.settings=list(superpose.points=list(col=rainbow(7)),
superpose.lines=list(col=rainbow(7))))
Valuable lessons learned here. Again, thanks.
Rich
