ARD Attributes

Source: R/ard_attributes.R
ard_attributes.Rd

Add variable attributes to an ARD data frame.

  • The label attribute will be added for all columns, and when no label is specified and no label has been set for a column using the label= argument, the column name will be placed in the label statistic.

  • The class attribute will also be returned for all columns.

  • Any other attribute returned by attributes() will also be added, e.g. factor levels.

Usage

ard_attributes(data, ...)

# S3 method for class 'data.frame'
ard_attributes(data, variables = everything(), label = NULL, ...)

# Default S3 method
ard_attributes(data, ...)
