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, variables = everything(), label = NULL)

Arguments

data

variables

(tidy-select)

label

(named list)
named list of variable labels, e.g. list(cyl = "No. Cylinders"). Default is NULL

Examples 

df <- dplyr::tibble(var1 = letters, var2 = LETTERS)
attr(df$var1, "label") <- "Lowercase Letters"
