The interesting R implementation for Normalization and Standardization is here now.
Here we check whether we need to go for Normalization or Standardization, for which we take one variable and go for histogram and check whether that variable is skewed or normally distributed. see below

Normality Check

Checked for price and Distance After Executing above , we know that variables are skewed, Standardization is not possible. So we opt for Normalization.

Dataset After Standardization

Here we end up with Feature Scaling, and we will head up with sampling Techniques in next page.
