collapse_vector.Rd
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)
An array of values. Can be NULL
. Required.
A single character element, where the values are separated by
commas. Can be blank. (i.e., ""
).
