Dear all,
Given such vector of array.
tags <- c("aaa", "ttt", "ccc", "gcc", "atn")
How can I obtain a matrix corresponding to it
[,1] [,2] [,3]
[1,] 0 0 0
[2,] 3 3 3
[3,] 1 1 1
[4,] 2 1 1
[5,] 0 3 0
In principle:
1. Number of Column in matrix = length of string (= 3)
2. Number of Row in matrix = length of vector ( =4).
3. Character "a" encode as "0",
"c" -> "1",
"g" -> "2",
"t" -> "3"
"n" -> "0"
Length of strings are assumed to be uniform within the vector,
and it can be greater than 3 (up to 40 characters).
