[R] model diagnostics for logistic regression

[Dylan Beaudette]

Greetings,

I am using both the lrm() {Design} and glm( , family=binomial()) to perform a 
a logisitic regression in R. Apart from the typical summary() methods, what 
other methods of diagnosing logistic regression models does R provide? i.e. 
plotting an 'lm' object, etc. 

Secondly, is there any facility to calculate the R^{2)_{L} as suggested by 
Menard in "Applied Logistic Regression Analysis" (2002) ?

Any thought would be greatly appreciated.

Cheers,
