[R] Problem with reading file saved in directory

[William Dunlap]

Reading the file with row.names=1 meant to make rownames out of the first
column in the text file.  Duplicate row names are not accepted.  To
diagnose, read it with row.names=NULL and see what is in the first column
(e.g., use the table function on it).
