R string functions
Hi,
I have a string "GGGGGGCCCAATCGCAATTCCAATT"
What I want to do is to count the percentage of each letter in the string,
what string functions can I use to count the number of each letter appearing
in the string?
For example, the letter "A" appeared 6 times, letter "T" appeared 5 times,
how can I use a string function to get the these number?
thanks,
karena
