The expression matrix (x), feature data (f), and phenotype data (p) are loaded in your workspace.

Subset x to only include the first gene (i.e. row) and insert it left of the ~ in the formula (y-axis).
Subset p to only include the column "Disease" and insert it right of the ~ in the formula (x-axis).
Subset f to only include the first gene (i.e. row) and the column "symbol". Use this as the argument to main for the plot title.
