Hi,
I am trying to rearrange the following data
d.f <- data.frame(x=c(1,1,2,2), y=c(1,2,1,2), vals=c("a11", "a12",
"a21", "a22"))
to look like a table with x as the rows and y as the columns, something like
y 1 2
x
1a11 a12
2a21 a22
I tried doing this
perfect. thank you Andy!
reshape() should do it:
> d
V1 V2 V3 V4 V5
1 A1 B1 C1 D1 E1
2 A2 B2 C2 D2 E2
3 A3 B3 C3 D3 E3
> d2 <- reshape(d, varying=list(names(d)[1:4]), direction="long")[c(3,1)]
> d2[order(d2$V5),]
V1 V5
1.1 A1 E1
1.2 B1 E1
1.3 C1 E1
1.4 D1 E1
2.1 A2 E2
2.2 B2 E2

Dear all:
I have this:
A1 B1 C1 D1 E1
A2 B2 C2 D2 E2
A3 B3 C3 D3 E3
And I want this
A1 E1
B1 E1
C1 E1
D1 E1
A2 E2
B2 E2
C2 E2
D2 E2
A3 E3
B3 E3
C3 E3
D3 E3
Example:
m<- matrix(1:15,nrow=3,byrow=T)
m
v<- unlist(list(t(m[,1:4])))
u<- rep(c(5,10,15),c(4,4,4))
data.frame(v,
