Hi
I realize that this is terribly basic, but I just don't seem to see it
at
this moment, so I would very much appreciate your help. How shall I transform this dataframe:
df1
Name Index Value 1 a 1 0.1 2 a 2 0.2 3 a 3 0.3 4 a 4 0.4 5 b 1 2.1 6 b 2 2.2 7 b 3 2.3 8 b 4 2.4 into this dataframe:
df2
Index a b 1 1 0.1 2.1 2 2 0.2 2.2 3 3 0.3 2.3 4 4 0.4 2.4
I have not seen an answer so I believe you look for: cast(df1, Index~Name, value = "Value") Regards Petr
df1 = data.frame(c("a", "a", "a", "a", "b", "b", "b", "b"),
c(1,2,3,4,1,2,
3,4), c(0.1, 0.2, 0.3, 0.4, 2.1, 2.2, 2.3, 2.4))
colnames(df1) = c("Name", "Index", "Value")
df2 = data.frame(c(1,2,3,4), c(0.1, 0.2, 0.3, 0.4), c(2.1, 2.2, 2.3,
2.4))
colnames(df2) = c("Index", "a", "b")
Thank you very much.
Dana
