[R] xYplot - plotting all factors

[John Poulsen]

Hello,

Sorry, I have used xYplot before and feel like this should be a very 
easy problem to solve.  But I keep hitting a snag.

I want the below code to plot three panels with different point 
estimates and their standard errors for each of five days.  I keep 
getting a warning message (see below) and only one panel of the graph is 
plotted:

Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf
3: In min(x) : no non-missing arguments to min; returning Inf
4: In max(x) : no non-missing arguments to max; returning -Inf

Thanks for any solutions!
John
