wconf: Weighted Confusion Matrix
Allows users to create weighted confusion matrices and accuracy
metrics that help with the model selection process for classification
problems, where distance from the correct category is important. The
package includes several weighting schemes which can be parameterized, as
well as custom configuration options. Furthermore, users can decide
whether they wish to positively or negatively affect the accuracy score
as a result of applying weights to the confusion matrix. Functions are
included to calculate accuracy metrics for imbalanced data. Finally,
'wconf' integrates well with the 'caret' package, but it can also work
standalone when provided data in matrix form.
