Question: Calculate and visualize some basic properties of gene expression levels in ALL dataset. Remember ... Calculate and visualize some basic properties of gene expression levels in ALL dataset. Remember that function exprs returns a matrix of gene expression levels (~13K genes) for each patient (>100 patients) in the sample.

a. Calculate average gene expression level for each patient. Plot them using the following visualizations:

i. Histogram

ii. Boxplot

iii. Stripchart

iv. Stem-and-leaf

v. Dotchart vi. Sorted in ascending order

b. Calculate average gene expression levels for each gene. Plot them using:

i. Histogram

ii. Boxplot

iii. sorted in the ascending order
