[R] script execution stops and give the error

[Neha gupta]

This is the whole code I provided except the libraries such as

library(caret)
library(randomForest)

data=read.csv("fault.csv")

inTraining <- createDataPartition(data$bug , p = .75,list = FALSE)
training <- data [inTraining, ]
testings <- data [-inTraining, ]
ctrol = trainControl(method = "repeatedcv", number=5)
myTrain <- train(bug ~ ., data = training,
                     method = "rf",
                    tuneLength = 15,
                     metric = "MAE",
                     preProc = c("center", "scale", "zv"),
                     trControl = ctrol)
