[R] kernel density estimation and classification

Hi, I am interested to use Kernel Density Estimation on bivariate data for multi-class classification. So far, I have managed to use the 'ks' package to plot the contours of the kernel density estimates based on 8-class training dataset with only 2 variables. However, I do not know how to m

[R] splitting dataframe, assign to new dataframe, add new rows to new dataframe

Hi, all, My objective is to split a dataframe named "cmbine" according to the value of "classes". After the split, I will take the first instance from each class and bin them into a new dataframe, "df1". In the 2nd iteration, I will take the 2nd available instance and bin them into another new
