Thank you Petr,
It kinda works, but not completely. The problem is that it produces a
column for each value ("Moyenne"), and not each element of
"Elem". That
means I have only one value per column, instead of up to 3.
For example, I have 3 columns for Al1670 instead of just one, and each
column contains maximum one value (the others being NA).
Not sure I am being clear...
By the way, I don't understand why my solution did not work; what is
wrong there?
Thank you again!
Ivan

Hi I looked into docs to reshape2 and played around a bit and by some magical feature test <- dcast(mm, Etape+Ech+repet+dilution+Rincage~Elem) probably works as you expect.

Thanks Petr,
It looks good, but I have to check in more details.
Can anyone help me with my original solution using reshape()? I'd like
to understand what I did wrong.
reshape(mydata, timevar="Elem",
idvar=c("Etape","Ech","repet","dilution","Rincage"),
direction="wide",
drop=c("ID","Nom_ech"))
Thank you in advance
Ivan
