What is the type of df[i] ?
i.e. what does it says:
SEXP tmp = df[i] ;
Rprintf( "TYPEOF(tmp)=%d", TYPEOF(tmp) ) ;
If this is anything but REALSXP (i.e. 14), then you have to coerce the
data to bne able to use it as a NumericVector.

Hi,
MY application is performing really slow due to unnecessary calls to
coerceToReal from this line NumericVector ocol = df[j]. Here is a sample

Please note that the data in df is float data.
