Question: More work on the Golub data set. (a) Save the expression values of the first five genes (in the first five rows) for the AML

More work on the Golub data set.

(a) Save the expression values of the first five genes (in the first five rows) for the AML patients in a csv file AML5.csv.

(b) Save the expression values of the first five genes for the ALL patients in a plain text file ALL5.txt.

(c) Compute the standard deviation of the expression values on the first patient, of the 100th to 200th genes (total 101 genes).

(d) Compute the standard deviation of the expression values of every gene, across all patients. Find the number of genes with standard deviation greater than 1.

(e) Do a scatter plot of the 101th gene expressions against the 102th gene expressions, label the x-axis and the y-axis with the genes biological names using xlab= and ylab= control options.
