Sorry Guys, i press the wrong button to send out the uncompleted message.

let me do it again.

I have a data set containing :

pclass:  A factor giving the class of the passenger: one of 1st, 2nd, 3rd.
age:      The age of the passenger in years.
sex:      Passenger's gender: female or male
age.group:        Passengers age group, one of 0‐9 , 10‐19, 20‐29,
30‐39, 40‐49, 50‐59, 60‐69,70‐79
survived:            Passenger's survival (1=survived, 0=did not survive)

Ignoring the variable age,
- I need to group the data into groups corresponding to each
age‐group/sex/class combination,
- I need to compute the logits for each combination.
- Make a data frame containing the logits, and the categorical
variables. I need to have one line in the data frame for each
combination of the factor levels.

Can someone please help with the R code for above???!!!

Thanks millions!!

Cheers
Andyer.
