Hi Benoit,

If you are in the directory that contains your data, you can use

> NC60 = read.table("NC60.DATA")
# there are some arguments you can use in "read.table"

OR

>NC60 = read.table("path to your data/NV60.DATA")


> yo(NC60)

By the way, I do not know your "LgmFormula". I think you already defined it.
