[R] Bug in RODBC ?

It seems that RODBC has a problem : when reading through ODBC from an Access
table with missing values, *character* missing values are (correctly) reported
as NA factor values. *Numeric* values, however, retain the value of the same
variable in the previous row.
My setup : R 1.1.1 under Win95, RODBC as compiled with the R Win CRAN
distribution, MS Access 97.
I just discovered this, and had no time to explore. I will try to debug this,
but my knowledge of the ODBC internals and gizzards being almost non-existent,
any clue from you would help me tremendously.
Is there a formal mechanism for bug reports ? If so, should I submit one ?
