[R] Odp: duplicate row.names are not allowed

[Petr PIKAL]

Hi

No error message? It seems to me that it is OK. There is of course limited 
width for printout on screen (see GUI preferences/console columns), and 
therefore everything which exceeds specified limits is printed on second 
and subsequent row.

try

dim(form1) or str(form1) for evaluation of your read data frame.

Regards
Petr
