Hi,
after looking around I was not able to get info about these two questions:

1. Is there a function to have a  "jackknifed corrected  var/cov estimate" (as 
described in MacKinnon and White 1985) in a standard OLS regression? 

2. Does R possess a LAD (Least Absolute Deviation) regression function?

Any help?
Thanks
