What I'm seeing here is the likelihood that the data object has been input 
incorrectly (or is a mess in the original file?) There appear to be commas in 
what would presumably be a numeric column and a column name with spaces in it. 
There is also misregistration of some lines of data possible with 
tab-characters that were eaten by Nabble's interface.  If you want help under 
these circumstances you should either respond with the first 20 lines of the 
original data file posted through a mail-client bypassing Nabble or post dput( 
head(objname, 20))
