valsIn contains a vector of all the parameters from the function call in the SQL query.
Depending on your function, you may wish to be able to handle many different types of input. A good way to handle this is to have a series of if..else..if statements comparing the input type and dealing with each separately. For instace, if you want to handle multiple numeric types, you might use::
