Reporting the information of EDA with html

The eda_web_report() report the information of exploratory data analysis for object inheriting from data.frame.

eda_web_report(.data, ...)

# S3 method for data.frame
eda_web_report(
  .data,
  target = NULL,
  output_file = NULL,
  output_dir = tempdir(),
  browse = TRUE,
  title = "EDA",
  subtitle = deparse(substitute(.data)),
  author = "dlookr",
  title_color = "gray",
  logo_img = NULL,
  create_date = Sys.time(),
  theme = c("orange", "blue"),
  sample_percent = 100,
  is_tbl_dbi = FALSE,
  base_family = NULL,
  ...
)

Arguments

.data

a data.frame or a tbl_df.

...

arguments to be passed to methods.

target

character. target variable.

output_file

name of generated file. default is NULL.

output_dir

name of directory to generate report file. default is tempdir().

browse

logical. choose whether to output the report results to the browser.

title

character. title of report. default is "EDA".

subtitle

character. subtitle of report. default is name of data.

author

character. author of report. default is "dlookr".

title_color

character. color of title. default is "gray".

logo_img

character. name of logo image file on top left.

create_date

Date or POSIXct, character. The date on which the report is generated. The default value is the result of Sys.time().

theme

character. name of theme for report. support "orange" and "blue". default is "orange".

sample_percent

numeric. Sample percent of data for performing EDA. It has a value between (0, 100]. 100 means all data, and 5 means 5% of sample data. This is useful for data with a large number of observations.

is_tbl_dbi

logical. whether .data is a tbl_dbi object.

base_family

character. The name of the base font family to use for the visualization. If not specified, the font defined in dlookr is applied. (See details)

Value

No return value. This function only generates a report.

Details

Generate generalized EDA report automatically. This feature is useful for EDA of data with many variables, rather than data with fewer variables.

Reported information

Reported from the EDA is as follows.

• Overview

  • Data Structures

  • Data Types

  • Job Informations

• Univariate Analysis

  • Descriptive Statistics

  • Normality Test

• Bivariate Analysis

  • Compare Numerical Variables

  • Compare Categorical Variables

• Multivariate Analysis

  • Correlation Analysis

    • Correlation Matrix

    • Correlation Plot

• Target based Analysis

  • Grouped Numerical Variables

  • Grouped Categorical Variables

  • Grouped Correlation

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 the dataset
heartfailure2 <- dlookr::heartfailure
heartfailure2[sample(seq(NROW(heartfailure2)), 20), "sodium"] <- NA
heartfailure2[sample(seq(NROW(heartfailure2)), 5), "smoking"] <- NA

# create html file. file name is EDA_Report.html
eda_web_report(heartfailure2)

# file name is EDA.html. and change logo image
logo <- file.path(system.file(package = "dlookr"), "report", "R_logo_html.svg")
eda_web_report(heartfailure2, logo_img = logo, title_color = "black",
  output_file = "EDA.html")

# file name is ./EDA_heartfailure.html, "blue" theme and not browse
eda_web_report(heartfailure2, target = "death_event", output_dir = ".", 
  author = "Choonghyun Ryu", output_file = "EDA_heartfailure.html", 
  theme = "blue", browse = FALSE)
}
