transformation_report | R Documentation |
The transformation_report() report the information of transform numerical variables for object inheriting from data.frame.
transformation_report(
.data,
target = NULL,
output_format = c("pdf", "html"),
output_file = NULL,
output_dir = tempdir(),
font_family = NULL,
browse = TRUE
)
.data |
a data.frame or a |
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. |
output_format |
report output type. Choose either "pdf" and "html". "pdf" create pdf file by knitr::knit(). "html" create html file by rmarkdown::render(). |
output_file |
name of generated file. default is NULL. |
output_dir |
name of directory to generate report file. default is tempdir(). |
font_family |
character. font family name for figure in pdf. |
browse |
logical. choose whether to output the report results to the browser. |
Generate transformation reports automatically. You can choose to output to pdf and html files. This is useful for Binning a data frame with a large number of variables than data with a small number of variables. For pdf output, Korean Gothic font must be installed in Korean operating system.
No return value. This function only generates a report.
The transformation process will report the following information:
Imputation
Missing Values
* Variable names including missing value
Outliers
* Variable names including outliers
Resolving Skewness
Skewed variables information
* Variable names with an absolute value of skewness greater than or equal to 0.5
Binning
Numerical Variables for Binning
Binning
Numeric variable names
Optimal Binning
Numeric variable names
See vignette("transformation") for an introduction to these concepts.
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")

transformation_report(heartfailure, death_event, output_format = "html",
output_file = "Transformation_heartfailure.html")
