Vectors shrub volume vectors (solution)

NoteExercise

You have data on the length, width, and height of 10 individuals of the yew Taxus baccata stored in the following vectors:

shrub_length <- c(2.2, 2.1, 2.7, 3.0, 3.1, 2.5, 1.9, 1.1, 3.5, 2.9)
shrub_width <- c(1.3, 2.2, 1.5, 4.5, 3.1, 2.6, 1.8, 0.5, 2.0, 2.7)
shrub_height <- c(9.6, 7.6, 2.2, 1.5, 4.0, 3.0, 4.5, 2.3, 7.5, 3.2)

Copy these vectors into an R script and then use R to determine the following:

  1. What is the maximum height of a shrub?
  2. What is is the width of the 6th shrub?
  3. How many shrubs are there?
  4. What is the average width of a shrub?
  5. What are the lengths of shrubs 3-5? (look up all values at once, not one at a time)
  6. What is the total height of all shrubs added together?
