A preprint of the article about auditor is available on arxiv.
devtools::install_github("mi2datalab/auditor")
Run the code below or try the auditor by the online jupyternotebook:
library(auditor)
library(randomForest)
data(mtcars)
# fitting models
model_lm < lm(mpg ~ ., data = mtcars)
set.seed(123)
model_rf < randomForest(mpg ~ ., data = mtcars)
# creating a modelAudit object which contains all necessary components required for further processing
au_lm < audit(model_lm)
au_rf < audit(model_rf, label = "rf")
# generating plots
plot(au_lm, type = "Residual")
plot(au_lm, au_rf, type = "Residual")
plot(au_lm, au_rf, variable = "wt", type = "Prediction")
plot(au_lm, au_rf, type = "ModelCorrelation")
plot(au_lm, au_rf, variable = "wt", type = "ModelCorrelation")
# plots above are availible also via plotResidual(), plotPrediction() and plotModelCorrelation() functions
