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

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.
I cannot comment your solution as I use reshape only sparsely.
Cheers

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!

Hi
I am not sure if I got it
library(reshape2)
mm<-melt(mydata, measure.vars="Moyenne") test <- dcast(mm,

gives me 3 rows but names need some tweaking afterwards.

Subject: [R] help with reshape
Dear users,
I'm having troubles with reshaping a data.frame from long to wide
format.
I copy the output of dput() at the end of the mail because it is
quite long.
Each row of the column "Elem" should be transposed to a new
column.
All variables "Etape", "Ech", "repet", "dilution", "Rincage"
define
the samples. Meaning that for each unique combination of these
variables, I want a single row, and as many columns as elements in
"Elem".
So I tried:
reshape(mydata, timevar="Elem",
idvar=c("Etape","Ech","repet","dilution","Rincage"),
direction="wide",
drop=c("ID","Nom_ech"))
The problem is that some columns are not used at all for defining
samples. In this case, the row "S1, F10-3, NA, 1, oui" is missing,
but I don't understand why.
Can you help me with that? I have no idea what I am doing wrong...
Thanks in advance,
Ivan
