Dear Arnaud,
I just played around with your data a bit and found this to be useful. But
kindly note that I am NO expert like the other people in the group. My answer
to you is purely for help purposes. My knowledge in R too is limited. I used
the reshape function and arrived at something. I am sure others will arrive at
a better and more crisp answer that I have. Again please note: I am only a
novice.
x <- c('A', 'B', 'C', 'A', 'B', 'C')y <- c(10, 5, 9, 5, 15, 20)df <-
data.frame(x,y)dff <- reshape(df, v.names = "y", idvar = "x", timevar = "y",
direction = "wide")
RESULT:
> f x y.10 y.5 y.9 y.15 y.201 A 10 5 NA NA NA2 B NA 5 NA 15
> NA3 C NA NA 9 NA 20
Hope this is of any use.
Kind Regards,
s.
