  font_family = NULL,
  browse = TRUE
)

Arguments

.data

a data.frame or a tbl_df.

target

target variable. If the target variable is not specified, the method of using the target variable information is not performed when the missing value is imputed. and Optimal binning is not performed if the target variable is not a binary class.

Value

No return value. This function only generates a report.

Reported information

The transformation process will report the following information:

See vignette("transformation") for an introduction to these concepts.

Examples

if (FALSE) {
# reporting the Binning information -------------------------
# create pdf file. file name is Transformation_Report.pdf & No target variable
transformation_report(heartfailure)

# create pdf file. file name is Transformation_Report.pdf
transformation_report(heartfailure, death_event)

# create pdf file. file name is Transformation_heartfailure.pdf
transformation_report(heartfailure, "death_event", 
                      output_file = "Transformation_heartfailure.pdf")

# create html file. file name is Transformation_Report.html
transformation_report(heartfailure, "death_event", output_format = "html")

# create html file. file name is Transformation_heartfailure.html
transformation_report(heartfailure, death_event, output_format = "html", 
                      output_file = "Transformation_heartfailure.html")
