Discretize Entire Columns

To use the Data frame in Julia, first, we need to install the Data frame package. We'll install the Data frame package as shown in the given code snippet. We can easily create a data frame using the DataFrame() function. DataFrame() function takes column and their values as argument. To Discretize entire columns at a time, use the given method as shown below.

using Pkg
Pkg.add("DataFrames")
using DataFrames
data_frame = DataFrame(c1 = 1:5, c2 = 5:10 , c3 = 10:15, c4 = 15:20)
data_frame
data_frame[!, :c1] = round.(Integer, data_frame[!, :c1])
data_frame[!, :c2] = round.(Integer, data_frame[!, :c2])
