[R] axis names in triangle.plot

[Stéphane Dray]

Hi Thomas,
This looks quite strange. By default, the function use the column names 
as labels.
What is grain ? A data.frame ? Why have you duplicated row.names? Please 
return the results of class(grain) and names(grain)

Cheers,
PS: If you have questions related to ade4, you can use the adelist
