1. I have put the data set loess2.csv on the website. Use the data to run loess plots using spans of .1, .3, .5, .7 and .9. Give the loess plot with the different spans using the lines option in R.
2. Consider the following are data from 3 arrays 6 spots each. Give the quantile-normalized array values.
spot 1 2 3 4 5 6
array1 5.390 12.074 3.247 4.274 11.24 14.861
array2 5.813 8.777 2.914 2.736 6.398 23.020
array2 7.522 7.719 1.783 10.59 4.439 21.972
3. I have put the data set for the craig.zip on the website. Download the files and do M versus A plots, boxplots and histograms with and without normalization. Use the methods discussed in class, MAS5 and RMA for normalization.
