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".  

 

 

 

 

> XTTable <- xtabs( ~   direction_ , SurveyData)

> XTTable

direction_

EASTBOUND                                          

                                               345 

WESTBOUND                                          

                                               307 

> EBSurvey <- subset(SurveyData, direction_ == "EASTBOUND" )

> XTTable <- xtabs( ~   direction_ , EBSurvey)

> XTTable

direction_

EASTBOUND                                          

                                                 0 

WESTBOUND                                          

                                                 0 

> EBSurvey <- subset(SurveyData, direction_ = "EASTBOUND" )

> XTTable <- xtabs( ~   direction_ , EBSurvey)
