1. [True or False] True or false? Consider that we call the function using the below statement: [x, y ,z] = f(vec, i) a. x is the maximum value of all elements of the input vector. True False

Question: (Related to R-language)-Looking answer to the below question. "Given a numeric vector x of arbitrary length,  write code to create a vector y that contains the squares of the values of x (note: x and y will have the same length). Your solution should not involve more than a couple of lines of code" .

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).

Problem 1 (a) Create a vector "v" containing elements in the order given: "Monday", "Wednesday" and "Friday". (b) Print the vector "v" and print what its type is. (c) Use the R help to learn about the substr function. Use it to obtain the first 3 letters of each element of the vector "v". Save it as a new vector "firstthree" and print "firstthree". (d) Finally, print the second element of the vector "firstthree"
