Packages and settings – R and Python

The R package LearnEDA is not available anymore and we need to work around it. To get over that problem, the three required functions lval, rline, and han are saved in a LearnEDA_Functions.R file and it is loaded as a source file:

1. First set the working directory:

   setwd("MyPath/R/Chapter_04") 

2. Install the R packages aplpack and vcd in the usual way, and run the following codes to set up the required packages:

   library(RSADBE)
   library(aplpack)
   library(vcd)
   source("SRC/LearnEDA_Functions.R")

   We have the usual Python packages as a pre-requisite.

3. Import the required Python packages as follows:
   

We are now set to carry out the desired analyses.
