incorporate_attr {dataMeta}

Incorporate attributes as metadata to an original dataset.

Description

incorporate_attr adds attributes to an original dataset as metadata, including a data dictionary, among other attributes. This is the third function used in this package. For the function to run, the following parameters are needed.

Usage

incorporate_attr(my.data, data.dictionary, main_string)

Arguments

my.data

Data.frame. The data set to add attributes as metadata.

data.dictionary

Data frame. The data dictionary has all variable names, and variable descriptions that will explain an original dataset.

main_string

A character string describing the original dataset.

Value

This function will return an R dataset containing metadata stored in its attributes. Attributes added will include: a data dictionary, number of columns, number of rows, the name of the author or user who created the dictionary and added it, the time when it was last edited and a brief description of the original dataset.

Examples

# example original data set for which a dictionary will be made
data("esoph")
my.data <- esoph

# Linker: Add description for each variable names and variable type
variable_description <- c("age group in years", "alcohol consumption in gm/day", 
"tobacco consumption in gm/day", "number of cases (showing range)", 
"number of controls (showing range)")
variable_type <- c(0, 0, 0, 0, 0)
linker <- build_linker(my.data = my.data, variable_description = variable_description, 
variable_type = variable_type)
linker

# Data dictionary
# For this data set, no further option description is needed.
dictionary <- build_dict(my.data = my.data, linker = linker, option_description = NULL, 
prompt_varopts = FALSE)
dictionary

# Create main_string for attributes
main_string <- "This dataset describes tobacco and alcohol consumption at different age groups."
complete_dataset <- incorporate_attr(my.data = my.data, data.dictionary = dictionary, 
main_string = main_string)
complete_dataset
attributes(complete_dataset)
