how to manipulate dput output format
...make dput dump rownames and colnames on
two separate lines, but i don't think it's possible. To give a specific

"RNT.A", "ADVA", "AAPL", "AAS", "ABFS", "ABM", "ABT", "ACI",...

sql server & linux: left join problem
I''ve got a left join problem of some sort connecting from linux
FreeTDS/ODBC to SQL Server. It''s similar to the false post I had
earlier, but this is a real problem. Here''s my code:
