2. Using a for loop, find the length of the dengue genome. To do this, outside of the for loop first define the variable length <- 0. Then with a for loop, iterate over each element of dengue vec , and with each iteration add 1 to length . This should look very similar to the body of the while loop just before part 6. i <- 1 while(i <= 10){ print(i^2) i <- i + 1 i i

Question

I have a vector labeled Dengue_Vec. I need to code a for loop that will provide me with the number of characters in that vector. The characters are nucleotides so they are letters. 

-The first image is the clear question and the second one is while loop referenced in the question.

thank you 

(I mainly don't understand how to iterate over nonnumerical values in a vector using the for loop or the while loop).
