Dear R-Users,
I store my data in an Postgres-table.
I can connect with Rdbi.PgSQL, that is no the problem.
The problem is the NA-Values. No-data-values are coded as -9999 in the
But when I extrct them with any SELECT-statement, the -9999-values are
treated as normal vectors.
How can I tell R not to fetch the datasets containig -9999-values?

thanks for your help
