Hello,  I have a question about DBI package.    Why  DBI::dbConnect(conn, 
trusted_connection = T)  works the same as  DBI::dbConnect(conn, 
trusted_connection = F  or  DBI::dbConnect(conn, trusted_connection = NA  ?  
This code will return connection via windows authentication. If I
want not to use windows authentication then I must ommit the paramter  
trusted_connection . It is hard to steer in my scripts cuz I must write a 
wrapper like this:  function ( drv ,  trusted_connection ,   # the rest of 
params) {
   if ( trusted_connection )   {
    DBI :: dbConnect ( conn ,  trusted_connection  =  T ,   # the rest of 
params)
   }   else   {
    DBI :: dbConnect ( conn ,   # the rest of params)
   }
 }  Happy Coding,  Wojtek
