Error image

Enoch Gyamfi Ampadu
Dear List,

Please I am undertaking land cover classification with the support vector
machine but output image have some portions appearing white. I have tried
both the *caret *and *e1071, *yet I got the same error image. Find below
the codes:

Caret package
modFit_svmR1999 <- train(as.factor(class) ~ B1 + B2 + B3 + B4 + B5 + B7,
data = TrainSet1999, method = "svmRadial")

e1071 package
modFit_svmR1999 <- svm(as.factor(class) ~ B1 + B2 + B3 + B4 + B5 + B7, data
= TrainSet1999)

Before running the above codes, I had done all the necessary image staking,
extracting of pixel values and data partitioning. I don't know what I am
not doing right and I will be glad to have some assistance.
Thank you
