squish: Returns a single-length vector if all values in vector are...

In martinctc/surveytools: Useful Support Functions for Survey Analysis

Returns a single-length vector if all values in vector are identical.

Description

This can be used with group_by() to transform data to a "higher" level with hierarchically structured data. For instance, one person may have multiple web visits, where all visits would have the same age and gender. Getting to the person-level data (each observation is a person) would require 'summarising'. squish() throws up an error message if values differ.

Usage

squish(x)

Arguments

x	A vector to be passed through, can be numeric or character.

Examples

## Not run: 
squish(c(1,2,1))

## End(Not run) 
squish(c(1,1,1))
