Reporting the information of data diagnosis with html

The diagnose_web_report() report the information for diagnosing the quality of the data.

diagnose_web_report(.data, ...)

# S3 method for data.frame
diagnose_web_report(
  .data,
  output_file = NULL,
  output_dir = tempdir(),
  browse = TRUE,
  title = "Data Diagnosis",
  subtitle = deparse(substitute(.data)),
  author = "dlookr",
  title_color = "gray",
  thres_uniq_cat = 0.5,
  thres_uniq_num = 5,
  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.

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 "Data Diagnosis Report".

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".

thres_uniq_cat

numeric. threshold to use for "Unique Values - Categorical Variables". default is 0.5.

thres_uniq_num

numeric. threshold to use for "Unique Values - Numerical Variables". default is 5.

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 Diagnosis. 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 data diagnostic reports automatically. This is useful for diagnosing a data frame with a large number of variables than data with a small number of variables.

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().
