Split Dataset into TrainSet & TestSet

Split Dataset into TrainSet & TestSet

  • In Library menu selects caTools
    • install that library by writing following line into R Script
      • install.packages('caTools')
      • only one time after comment it.
  • Select that library
  • Split data into TrainSet & TestSet

#split data into Train Set & Text Set
set.seed(123)
split = sample.split( dataset$Purchased , SplitRatio = 0.8)
train_set = subset( dataset , split==TRUE)
test_set = subset( dataset , split==FALSE)

  • If you write this code then it splits dataset into train_set & test_set
  • It generates train_set & test_set  Global variable data

Categorical Data Here in Data.csv, two column  are Categorical Data Country (France / Spain /Germany) Purchased (YES/NO) So we want to make categorical data. #categorical data dataset$Country = factor ( dataset$Country,                            levels = c('France','Spain','Germany'),                            labels = c(1,2,3)) dataset$Purchased =factor( dataset$Purchased ,                            levels =c('Yes','No'),                            labels = c(1,0)) Just add this line of code and run it, observe dataset variable. It assigns country column 1,2,3 to France, Spain, Germany. purchased column 1,0 to  Yes, No.
