show the right-false guess of a model in a graphic

[Mary1]

Hello colleagues,

I don´t know how to reflect in a ggplot and with different forms the output of the right guess or false guess data of a prediction model.

I have a test: testData and a prediction model: model_svm, that have done some predictions preds_svm.
I search the relation between x=Experience and y=Revenue, coloring in 3 colors depending of Comercial people.
I need to reflect in the graph with 2 different forms (ellipse and other) the right and false predictions.

The instruction I have prepared is correct by I can´t relfect the right-false data of the prediction model with different forms:

graph<-ggplot (testData, aes(x=Experience, y=Revenue, color=Comercial)) +
geom_point() +
geom_smooth(method=lm, aes(fill=Comercial))+
stat_ellipse(type = "norm")

Many thanks,
Mary

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.…
