Hi Joanna,
As you specified space (" ") as the field delimiter in your initial 
post, fields with spaces would be read as multiple fields, forcing the 
first column to be read as row names. I suspect that you changed the 
delimiter or that read.csv treats this differently from read.delim. I 
recall having to specify something about row names with read.delim once.
