Reshape function on R

Question

I have the following data frame on R:

Year	Result	Var1	Var2	Var3
2000	Positive	0.5	0.2	0.3
2000	Negative	0.4	0.2	0.5
2001	Positive	0.3	0.5	0.5
2001	Negative	0.3	0.2	0.3
2002	Positive	0.3	0.5	0.1
2002	Negative	0.3	0.2	0.4

I am seeking to create the following table:

Year	Var1.Positive	Var1.Negative	Var2.Positive	Var2.Negative	Var3.Positive	Var2.Positive
2000	0.5	0.4	0.2	0.2	0.3	0.5
2001	0.3	0.3	0.5	0.2	0.5	0.3
2002	0.3	0.3	0.5	0.2	0.1	0.4

To do so, I am using reshape:

dat$Result <- as.factor(dat$Result)


df = reshape(dat, idvar = "Result", timevar = "Year", direction = "wide")

But a table of NaNs is delivered. What am I missing?

Thanks !
