QUESTION

One hot fail - windows does not do one hot encoding

Asked 2021-Oct-19 at 21:09

I'm new to R and can not get my head arround why some very basic script does not perform one hot encoding in a windows-environment while it performs totally well in a linux-environment. As I have to work within the failing windows-environment I'd like to make the script perform one hot encoding.

This happenes within windows (one hot fail)

I think this has to do with your R versions, not the platform. One of the key defaults for creating data.frames, stringsAsFactors, got a new default (=FALSE) in R 4.0 after years of tripping up unsuspecting new users. However, some packages, such as it seems mltools, expect the kind of data frame that would be created using the old default, stringsAsFactors = TRUE. For more: https://developer.r-project.org/Blog/public/2020/02/16/stringsasfactors/index.html

I was able to replicate the problem and could fix it by setting stringsAsFactors = TRUE. (BTW, it looks like mltools::onehot expects a data.table as input, so I'm not sure there's a way to avoid using that package.)

As the error message implies, you should use either {'preds' and 'actuals'} or {'TP', 'FP', 'TN', 'FN'} or {'confusionM'}, but certainly not all of them togetner, as you are trying to do here.

Asked 2020-Feb-17 at 14:39

I have an issue of translating matrix into one hot encoding in R. I implemented in Matlab but i have difficulty in handling the object in R. Here i have an object of type 'matrix'.

I would like to apply one hot encoding to this matrix. I have problem with column names.

here is an example:

Your data table must contain some columns (variables) that have class "factor". Try this:
