collapse_vector function

Collapse a vector of values into a single string when necessary

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)

collapse_vector(elements)

Arguments

• elements: An array of values. Can be NULL. Required.

Returns

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

Examples

library(REDCapR) # Load the package into the current R session.
REDCapR:::collapse_vector(elements = NULL   )
REDCapR:::collapse_vector(elements = letters)
