spsspkg.processcmd Function (R)

spsspkg.processcmd(oobj,myArgs,f,excludedargs). Parses the values passed to the Run function associated with an extension command, and executes the implementation function.

• The argument oobj is a value returned by the Syntax function. It contains all of the information needed to parse the values passed to the Run function associated with an extension command.
• The argument myArgs should be specified as:

  myArgs = args[[2]]

  where args is the argument passed to the Run function. myArgs contains the run-time values of the keywords associated with the extension command.

• The argument f is the name of a function that implements the extension command.
• The argument excludedargs is an optional list of arguments to be ignored when checking for arguments required by the implementation function f.

Note: The spsspkg.processcmd function is used in conjunction with the implementation code for an extension command implemented in R. It is not for use within a BEGIN PROGRAM R-END PROGRAM block. Specifically, it is for use in the Run function that implements the extension command.

Information on creating extension commands is available from the following sources:

• The chapter on Extension Commands in Programming and Data Management for IBM SPSS Statistics , which is also available from the IBM SPSS Predictive Analytics community.
• A tutorial on creating extension commands for R is available from "Working with R" in the Help system.
