R Documentation

Collapse a vector of values into a single string when necessary

Description

REDCap's API frequently specifies a series of values separated by commas. In the R world, it's easier to keep these values as separate elements in a vector. This functions squashes them together in a single character element (presumably right before the return value is passed to the API)

Usage

collapse_vector(elements)

Arguments

elements

An array of values. Can be NULL. Required.

Value

A single character element, where the values are separated by commas. Can be blank. (i.e., "").
