Scalar Function and Scalar Function Factory R Interface
This section describes information that is specific to the R API. See R SDK API Documentation for general information about implementing Scalar functions.
Scalar Function API
The API provides the following framework for extension by R function:
FunctionName <- function(input.data.frame, parameters.data.frame) { # Computations # The function must return a data frame. return(output.data.frame)
}
Scalar Function Factory API
The API provides the following framework for extension by R function:
FunctionNameFactory <- function() { list(name = FunctionName, udxtype = c("scalar"), intype = c("int"), outtype = c("int")) }
For a complete list of factory options, see the R API documentation for Factory Function.
