gather_attrs: Gather attributes from data frame variables

Description

gather_attrs moves variable-level attributes to the data frame level and spread_attrs reverses that operation.

Usage

gather_attrs(x)

spread_attrs(x)

Arguments

x

A data frame.

Value

x, with variable-level attributes stored at the data frame level.

Details

import attempts to standardize the return value from the various import functions to the extent possible, thus providing a uniform data structure regardless of what import package or function is used. It achieves this by storing any optional variable-related attributes at the variable level (i.e., an attribute for mtcars$mpg is stored in attributes(mtcars$mpg) rather than attributes(mtcars)). gather_attrs moves these to the data frame level (i.e., in attributes(mtcars)). spread_attrs moves attributes back to the variable level.
