[R] Obtaining summary of frequencies of value occurrences for a variable in a multivariate dataset.

[Adaikalavan Ramasamy]

The name of the table should give you the "value". And if you have a 
matrix, you just need to convert it into a vector first.

 > m <- matrix( LETTERS[ c(1:3, 3:5, 2:4) ], nc=3 )
 > m
      [,1] [,2] [,3]
[1,] "A"  "C"  "B"
[2,] "B"  "D"  "C"
[3,] "C"  "E"  "D"
 > tb <- table( as.vector(m) )
 > tb

A B C D E
1 2 3 2 1
 > paste( names(tb), ":", tb, sep="" )
[1] "A:1" "B:2" "C:3" "D:2" "E:1"

If this is not what you want, then please give a simple example.

Regards, Adai
