3.19 Coding Questions

  1. Run the following code to create the data that we will use in the problem

    set.seed(1234) # setting the seed means that we will get the same results
    x <- rexp(100) # make 100 draws from an exponential distribution

    Use the ggplot2 package to plot a histogram of x.

  2. For this question, we’ll use the data fertilizer_2000. A scatter plot is a useful way to visualize 2-dimensional data. Use the ggplot2 package to make a scatter plot with crop yield (avyield) on the y-axis and fertilizer (avfert) on the x-axis. Label the y-axis “Crop Yield” and the x-axis “Fertilizer”. Do you notice any pattern from the scatter plot?
