I am using the SVM model for the classification of the data given below, but I don't know why I am getting this error. I have tried using two methods but both are not working. Please help me I am stuck for a very long. I have seen many posts here and tried to specify my model for classification but no results.

My data:

my code:

Model 1:

svm1 <- svm(class~., data = train, type = "C", kernal="radial", 
            gamma=0.1, cost=10)

Model 2:

x <- subset(np_2, select = -class) 
y <- np_2$class
model <- svm(x, y, probability = TRUE)
pred_prob <- predict(model, x, decision.values = TRUE, probability = TRUE)

Error:

Error in svm.default(x, y, probability = TRUE) : 
  Need numeric dependent variable for regression.

CodePudding user response：

Here you go. Next time try to include the libraries:

Just transform your class to a factor. In that case, the svm will convert it to numeric for you:

np_2 <- transform(np_2, class = factor(class))
trainX <- caret::createDataPartition(np_2$class ,p=0.8,list=FALSE)
train <- np_2[trainX,]
test <- np_2[-trainX,]

e1071::svm(class~.,data =train, type = "C", kernal="radial",gamma=0.1,cost=10)

which outputs:

Call:
svm(formula = class ~ ., data = train, type = "C", kernal = "radial", gamma = 0.1, cost = 10)


Parameters:
   SVM-Type:  C-classification 
 SVM-Kernel:  radial 
       cost:  10 

Number of Support Vectors:  16
