[R] Table and Sweave

[David Winsemius]

Is it possible that we do not have the full session code and that  
attach(df) was executed "off-stage" so to speak, or perhaps the OP is  
following an example where attach(df) was executed several pages  
earlier. The column names are being treated in the code as first class  
objects.
