I can never remember what melt, cast and all that means, hence I simpy
use reshape() which does not even require any additional package:
reshape(dat, direction="long", idvar = "ID",
varying=list(2:4), v.names="Value", times=names(dat)[2:4])

Hello,
I need to convert dataframe from:
ID T0 T1 T2
A 1 2 3
B 4 5 6
C 7 8 9
to:
ID Variable Value
A T0 1
A T1 2
A T2 3
B T0 4
B T1 5
B T2 6
C T0 7
C T1 8
C T2 9
i tried to use melt cast but it gives me all the time not exactly what I
need.
Thank you.
