KNN in R: 'train and class have different lengths'?

Question

Here is my code:

train_points <- read.table(\"kaggle_train_points.txt\", sep=\"\\t\")
train_labels <- read.table(\"kaggle_train_labels.txt\", sep=\"\\t         


        

Answer 1

Try converting the data into a dataframe using as.dataframe(). I was having the same problem & afterwards it worked fine:

train_pointsdf <- as.data.frame(train_points)
train_labelsdf <- as.data.frame(train_labels)
test_pointsdf <- as.data.frame(test_points)
