A reproducible example would get you more feedback.

Subject: [R] inverse function of melt
I'm looking for an inverse function of melt(which is in package reshape).Namely, I had a data frame like this
YEAR VAR1 VAR2 VAR3
1995 7 3 45
1996 5 6 32
1997 6 10 15
I transformed my data by using the melt function and my data was reshaped in the following format:
YEAR variable value
1995 VAR1 7
1996 VAR1 5
1997 VAR1 6
1995 VAR2 7
1996 VAR2 5
1997 VAR2 6
1995 VAR3 7
1996 VAR3 5
1997 VAR3 6
Now I would like to come back to the original format, namely table1.
Anyone could help me??
Thanks for your attention!
