Reported information

TThe transformation process will report the following information:

• Overview

  • Data Structures

  • Job Informations

• Imputation

  • Missing Values

  • Outliers

• Resolving Skewness

• Binning

• Optimal Binning

The base_family is selected from "Roboto Condensed", "Liberation Sans Narrow", "NanumSquare", "Noto Sans Korean". If you want to use a different font, use it after loading the Google font with import_google_font().

Examples

# \donttest{
if (FALSE) {
# create pdf file. file name is Transformation_Paged_Report.pdf
transformation_paged_report(heartfailure, sample_percent = 80)

# create pdf file. file name is Transformation_heartfailure. and change cover image
cover <- file.path(system.file(package = "dlookr"), "report", "cover2.jpg")
transformation_paged_report(heartfailure, cover_img = cover, title_color = "gray",
  output_file = "Transformation_heartfailure")

# create pdf file. file name is ./Transformation.pdf and not browse
cover <- file.path(system.file(package = "dlookr"), "report", "cover1.jpg")
transformation_paged_report(heartfailure, output_dir = ".", cover_img = cover, 
  flag_content_missing = FALSE, output_file = "Transformation.pdf", browse = FALSE)

# create pdf file. file name is Transformation_Paged_Report.html
transformation_paged_report(heartfailure, target = "death_event", output_format = "html")
}
# }
