Is there any easy way to normalize columns in dataframe?

[Lawrence]

I have a dataframe with several double type varaibles.

I tried to code the normalization by myself, by it seems mean() function do not consume non-numeric type data.

I planned to normalize the columns into minimal value 0 and maximum value 1, so the built in function scale() don't work for me. And I also have an Date column that need to be neglected.

Is there any normalize function that I could do this easily? Thank you!

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
