RMySQL and Stored procedures

Can someone provide me a good way to circumvent the lack of calling Stored Procedures from RMySQL? I can not rewrite those stored procedures on R because there a lot more folks here that only understands SQL. The stored procedure returns a resultset.
Use RODBC instead.
Assuming two stored procedures :
CREATE PROCEDURE getusers (in userid INT)
BEGIN
SELECT name from jos_users where id > userid;
END;
CREATE PROCEDURE getusers0()
BEGIN
SELECT name from jos_users;
END;
The following works
#####
library(RODBC)
con = odbcConnect("mysql",uid="xxx",pwd="yyy")
users0 = sqlQuery(con,"CALL getusers0")
users0
users = sqlQuery(con,"CALL getusers(20)")
users
close(con)
