Uses datashield.methods
function from DSI
package to list all
assign and aggregate functions on the available data repository servers.
The only choice of arguments is in datasources
; i.e. which studies to interrogate.
Once the studies have
been selected ds.listServersideFunctions
lists all assign functions for all
of these studies and then all aggregate functions for all of them.
This function does not call any server-side function.
ds.listServersideFunctions
returns to the client-side
a list containing all server-side functions separately for each study.
Firstly lists assign and then aggregate functions.
