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.

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. ######################### > > XTTable <- xtabs(wt_annual ~ time_strata + connector, LAWAData) > XTTable ## List connector time_strata OD Passenger Connector Morning Peak - 0550 to 0959 5605.140 1234.933 Late m...
