creating a contingency table from a data.frame automatically (NOT BY HAND)
...6 34 0 12 3...
of course, hunting.prev would only be needed to create the index via
hunting.prev=="success" and is here used to indicate what each row
means. My questions would be:
a) how to count and split each categorical variable by a response
variable, how to create a 2x20something (contingency) table and how far
a prop.test() approach or a chi? may be more appropriate to actually
analyze the data.
b) how do you guys create R output so that it's formatted in nice
columns and rows?
Hope to see help,
Thanks!
