dataset_visualize {madshapR}

Generate a web-based visual report for a dataset

Description

Generates a visual report of a dataset in an HTML bookdown document, with summary figures and statistics for each variable. The report outputs can be grouped by a categorical variable.

Usage

dataset_visualize(
  dataset = tibble(id = as.character()),
  bookdown_path,
  data_dict = data_dict_extract(dataset),
  group_by = NULL,
  valueType_guess = FALSE,
  taxonomy = NULL,
  dataset_name = .dataset_name,
  dataset_summary = .summary_var,
  .summary_var = NULL,
  .dataset_name = NULL
)

Arguments

dataset

A dataset object.

bookdown_path

A character string identifying the folder path where the bookdown report files will be saved.

data_dict

A list of data frame(s) representing metadata of the input dataset. Automatically generated if not provided.

group_by

A character string identifying the column in the dataset to use as a grouping variable. Elements will be grouped by this column.

valueType_guess

Whether the output should include a more accurate valueType that could be applied to the dataset. FALSE by default.

taxonomy

An optional data frame identifying a variable classification schema.

dataset_name

A character string specifying the name of the dataset (used internally in the function dossier_evaluate()).

dataset_summary

A list which identifies an existing summary produced by dataset_summarize() of the dataset. Using this parameter can save time in generating the visual report.

.summary_var

.dataset_name

Details

A dataset is a data table containing variables. A dataset object is a data frame and can be associated with a data dictionary. If no data dictionary is provided with a dataset, a minimum workable data dictionary will be generated as needed within relevant functions. Identifier variable(s) for indexing can be specified by the user. The id values must be non-missing and will be used in functions that require it. If no identifier variable is specified, indexing is handled automatically by the function.

A data dictionary contains the list of variables in a dataset and metadata about the variables and can be associated with a dataset. A data dictionary object is a list of data frame(s) named 'Variables' (required) and 'Categories' (if any). To be usable in any function, the data frame 'Variables' must contain at least the name column, with all unique and non-missing entries, and the data frame 'Categories' must contain at least the variable and name columns, with unique combination of variable and name.

The valueType is a declared property of a variable that is required in certain functions to determine handling of the variables. Specifically, valueType refers to the OBiBa data type of a variable. The valueType is specified in a data dictionary in a column 'valueType' and can be associated with variables as attributes. Acceptable valueTypes include 'text', 'integer', 'decimal', 'boolean', datetime', 'date'. The full list of OBiBa valueType possibilities and their correspondence with R data types are available using valueType_list. The valueType can be used to coerce the variable to the corresponding data type.

A taxonomy is a classification schema that can be defined for variable attributes. A taxonomy is usually extracted from an Opal environment, and a taxonomy object is a data frame that must contain at least the columns taxonomy, vocabulary, and terms. Additional details about Opal taxonomies are available online.

Value

A folder containing files for the bookdown site. To open the bookdown site in a browser, open 'docs/index.html', or use bookdown_open() with the folder path.
