Multiple Parameters
I would like to send a list of parameters to a UDF in addition to the data table.
I am using Vertica 6.1 and the statement USING PARAMETERS is useful, but the documentation only shows how to send a single parameter.
How do I deal with more than 1?
Example
SELECT a,b,add2Constants(a,b USING PARAMETERS c1 = 1, c2 = 2) OVER() FROM table;
a b sum
1 2 6
3 4 10
5 6 14
Current parametertypecallback is as follows (BTW you have an error in the documentation, you created PARAMS and used PARAM in the example.)

kmeansParameters <- function(){ param <- data.frame(datatype=rep(NA, 1), length=rep(NA,1), scale=rep(NA,1),name=rep(NA,1) ) param[1,1] = "int" param[1,4] = "k" param }
