[R] correlation between categorical data

[Dylan Beaudette]

Not an expert, but I would try some of the following:

# tabulate joint frequencies
?table
?xtabs

# plotting
mosaicplot(Titanic, main = "Survival on the Titanic", color = TRUE, shade=TRUE)

# log-linear models

check the library for more ideas.

Cheers,
Dylan
