No. The error is telling you that there is no object with the name  
'Wordata1.csv' in the R workspace.

Try quoting the file name (assuming such a named file is in your  
working directory.) It also doesn't make much sense and may even be an  
error to supply a sep="" argument to read.csv().

Well, there are surely examples where questioners have been told they  
needed to quote the 'file' argument, but there might be many other  
errors that created an invalid argument.
