The glossary describes the main objects used in Rmonize functions. The main 
components of each object are listed and must have the names as presented to be 
used in functions, except where indicated in square brackets ([…]). 
An asterisk (<strong>*</strong>) indicates a required object or component. You 
can download templates or find additional documentation where available using the 
links provided.
