R help - Jun 2005 - questions on bootstrap

Hi,

I would like to know:

1)  if there is a way of getting an R-squared value for a bootstrap 
crossvalidation. 
2) how I can get the total residual standard error  for a bootstraped model.

Thanks,

Caterina

Install the Design and Hmisc packages and look at documentation for ols 
and validate.ols.
