The description of the variables are as follows: total_bill: Final price of the meal Produce a one-way frequency distribution of the days when the customers had gone to the restaurant. Produce a two-way frequency distribution of the two variables day and time. Produce a three-way relative frequency distribution of the gender of the customer and whether they were at a smoking table by day on which they dined.Explanation / Answer
1) days=table(tablename$day);
class(days);
f1=as.data.frame(days);
2) An altrnate and easy way of doing this is to use library(plyr).
library(plyr)
f2=count(tablename, c('day','time'));
3) the three way frequency will be.
library(plyr)
f3=count(tablename, c('gender','table'));
