Build a query string from a set of named parameters

Usage

Arguments

parameters

A list with a set of key-value pairs to compose the query string

Value

A single string with the query string produced.

Details

This function takes a set of key-value pairs (or in other words, a set of named arguments), to build a query string. It basically combine (or "collapse") all key-value pairs together, to form the resulting query string.

Logical values (TRUE or FALSE) are automatically converted to a lower-case version ("true" or "false"), since these versions are more typically used in standard query strings.
