Simple (?) subset problem
I can't figure out the syntax I need to get subset to work. I'm trying
to split my dataframe into two parts. I'm sure this is a simple issue,
but I'm stumped. I either get all or none of the original "rows".

How do I get xtabs to show missing data?
...ataframe. How do I get them to list?
I found references to na.action and na.pass, but I could not figure out
how I could use them with xtabs to list the na as a value. I'm sure
there's a simple syntax I need, but it's not obvious to me.

Still can't find missing data
...a xtabs one way I have observations under "Connector" but against a different variable "Connector" shows all 0 values.
What is wrong? I've looked into the na commands and the ?xtabs entry, but I haven't found anything that works.

I can't get the syntax that will allow me to show NA values (rows) in the xtabs.
