You probably have non numeric data in your original CSV. Either you can 
correct it before reading it or you could try to force colClasses 
parameter of read.*whatever* you use and failed to tell.

Another option is to remove nonumeric items and change factors to numeric 

see
?as.numeric and ?as.character
