In R studio compute the following: compute a vector consisting of the elements of a vector x that are negative given two numeric vectors x and y of the same length, get a vector by adding the corresponding elements of x and y given a vector x of strings, compute a vector that is like x but with "baz" added to the end given a numeric vector x, compute a vector like x but sorted and with no duplicates (hint: R has a 'sort' function) compute a data frame by getting rows 3, 5, and 7 from the 'faithful data frame that is built into 1. 2. 3. 4. 5
