The `continent` column contains values like Oceania, which are better described as `world_region`
Current version of purrr (0.2.3) results in following error being thrown: ```r `cross_d()` is deprecated; please use `cross_df()` instead. ```
In general, a user will want to predict values and score/evaluated their fit after learning all models via `learn()`. The exact functions to do this are many. However, pipeable functions...
Currently, `predict.pipelearner` assumes that the output of `predict` on each fit will return a single vector of values. However, this isn't always the case. For example, default settings on `predict.rpart`...
Currently, `predict.pipelearner()` applies default `predict()` to each fit. However, sometimes this needs to be adjusted. For example, changing `predict` to produce probabilities or classes.
Many twidlr methods involve setting and getting a formula as an attribute. It's a bit messy in base code. Eg... ``` attr(object, "formula") ``` Instead, create wrapper functions like `set_formula`...
Some models literally retain copies of data frames etc in order to make predictions. This can be convenient but has at least two downsides (described below). This issue proposes that,...
`predict` should always return a set of predicted values that match the data. twidlr can support various tidy functionality by always ensuring that the returned result is a vector or...
Docs for twidlr of `e1071::svm()` need examples
After having removed the .data.frame S3 methods for all model functions (see commit 0801907f13634c40bff403cc3577bf5031e0c93c), it occurs that S3 methods may not be necessary at all! Instead of having .default, just...
