I know that mvrnorm from MASS (generously provided by Profs. Venables
and Ripley) can be used to generate multivariable normal data that can
be used in a linear regression with certain desired characteristics
(e.g. a given mean for each variable as well as a given
variance-covariance pattern). Is there any similar facility that can be
used to generate data for (1) a logistic regression and (2) a Cox
proportional hazards regression?  
Thanks,
John
