+1. To execute the R code of CondIndependentTest.R, you need do some preparation.
+   a.) Install package "bnlearn" in R, (because I used "bnlearn" package in my code.):
+       install.packages("http://www.bnlearn.com/releases/bnlearn_latest.tar.gz")
+   b.) Download file CondIndependentTest.R and put it in a folder (For example, put it in folder "/home/zgong001/Documents/SprinklerDataset/CondIndependentTest.R"). 
+2. Execute the code.
+   a.)In Console of R, you type in:
+      source("/home/zgong001/Documents/SprinklerDataset/Rcode/CondIndependentTest.R")
+      The content in "" is the location where you put file CondIndependentTest.R.
+      If there are some errors, you should double check the path is correct.
+   b.)In Console of R, you type in something like the following:
+      CondIndTwoVar(filename = "/home/zgong001/Documents/SprinklerDataset/sprinkler1001.txt", methodu="x2", exfilename = "/home/zgong001/Documents/SprinklerDataset/pvalueSorted(sprinkler).xlsx")
+      filename: is the full path and file name of your data file.
+      methoudu: is the method you'll choose to do conditional independence test. You could choose "x2" or "mi". "x2" means Chi-Square Test of Independence and "mi" means mutual information test.
+      exfilename: is the full path and excel file name which you want to output your test result.
