I sent a private reply to the poster yesterday with the solution to his
problem,
bit evidently he hasn't seen it, so ...
# Function to tabulate an amino acid sequence
# using strsplit and table:
AAtab2 - function(x) {
# Creates a frequency table of the characters in a string
AA -
Hi fadialnaji,
Take a look at the Biostring package in Bioconductor [1] It might be an
alternative to do what you want.

may some one please help me to sort this out, i am trying to writ a R code
for calculating the frequencies of the amino acids in 9 different sequences,
i want the code to read the sequence from external text file, i used the
following code to do so:
x-read.table(sequence.txt,header=FALSE)
then i

i know it would be better to ask R to make the data, but i need to sequence
this particular file, because it is data for some Amino Acids and i cant
play with, so i need to ask R to go through the sequence one by one, and
then give me the numbers of each letters of each sequence, i am quite
