You can go to this directory to find the files needed for the case study.
ftp://111.198.139.72:4000/PhosMap/data/
Or download them directly through the following links.
This .zip contains PhosMap's demo code and raw datasets. After unzip, start the R program with setting the new folder as your working directory, and run the R script in it.
ftp://111.198.139.72:4000/PhosMap/data/PhosMap_Demo_With_BRAFi_Data.zip
The .RData file stores the input objects required to invoke functions in the PhosMap script demo, which can be downloaded from the following link.
ftp://111.198.139.72:4000/PhosMap/data/BRAFi.RData
After downloading, put it into your working directory. Use the following command to introduce these objects into the global environment, then you can smoothly execute the statements in the script.
