bio325 guest lecture, yeast oxidative stress analysis

Try to lead students work on Rmd file for yeast gene expression data analysis

It turns out that the bioconductor packages are not supported by the recent R3.2.4. I had to lead students to use R3.2.3.

Among the students, there are 7 Apple laptops and 2 windows laptops.

I made a mistake when going through probes on Affymetrix Yeast 2.0 chip. It contains 2 MSH2 genes, on for S cerevisiae and one for S pombe.
