[R] RODBC package -- sqlQuery(channel,.....,nullstring=0) still gives NA's

[Luis Rideau Cruz]

R-help,

I'm using the RODBC package to retrieve data froma ODBC database which
contain NA's.

By using the argument nullstring = "0"  in sqlQuery() I expect to
coerce them to numeric but still get NA's in my select.

I'm running on Windows XP
