reshape long format to wide format by ""COUNT".. How can I make it?
Question
I'm a R beginner
I have a dataframe as following below
I want reshape dataframe above like this .. by "Dataframe format"
I know i can make it by 'table function' table(incomegr=edu.q$incomegr,edu.q$langgr) but this format is 'table' not 'dataframe'
ie, i want make each 'incomegr', 'Gr9', 'Gr8' as dataframe columns.
