I have a data table, and I try Reshaping it but it doesn\'t work, how do I do this:

I have a data table:

Name | Value

Answer 1

 res <- read.table(text="Name | Value
 Bob  | 8,9,10
 Mike | 2,3,4
 Sandr| 5,6,7", header=TRUE, sep="|")
dres <- data.frame(Value= unlist( strsplit(as.character(res$Value), ",") )
, Name=rep(res$Name, each=3))
dres <- dres[order(as.numeric(as.character(dres$Value))), ]
dres
outer(sort(dres$Value), sort(dres$Value), FUN=function(x,y) dres[x, "Name"] == dres[y,"Name"] )
       [,1]  [,2]  [,3]  [,4]  [,5]  [,6]  [,7]  [,8]  [,9]
 [1,]  TRUE  TRUE  TRUE FALSE FALSE FALSE FALSE FALSE FALSE
 [2,]  TRUE  TRUE  TRUE FALSE FALSE FALSE FALSE FALSE FALSE
 [3,]  TRUE  TRUE  TRUE FALSE FALSE FALSE FALSE FALSE FALSE
 [4,] FALSE FALSE FALSE  TRUE  TRUE  TRUE FALSE FALSE FALSE
