1. Write a for loop that will print the cubes of the integers 5 through 33. Be sure to show all results. ```{r} ``` a. Write a loop that will compute the cubes of all integers 5 through 33, but store the results in a vector, named cubes. Display the contents of cubes after you create it. ```{r} ``` b. Write a loop that will compute the medians of each of the numeric columns of the iris dataset. Store the result in a vector called iris.medians. Name the entries of the vector for extra readability, and display the result. ```{r} ``` c. Read in the *microbiome* dataset that is posted on Moodle. The dataset contains (gut) microbial abundances of certain phyla of bacteria. The hypothesis is that body mass index (BMI) may be correlated to abundances of certain phyla is the reason for this dataset. The dataset has been simplified include only 25 subjects and the abundances of 4 of the most abundant phyla: bacteroidetes, firmicutes, proteobacteria, and actinobacteria..
