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,u)  

 
 

This is the result I want but I would like to learn a simpler way to do it. Any clue?  

 
 

Thanks  

 
 

j. silva
