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)
> XTTable
direction_
EASTBOUND
345
WESTBOUND
307
> EBSurvey <- subset(SurveyData, direction_ == 1 )
> XTTable <- xtabs( ~ direction_ , EBSurvey)
> XTTable
direction_
EASTBOUND
0
WESTBOUND
0
