R help - Apr 2012 - output of several "results" from a function

Hi,

I try my first time to write a summary method for my function. The result of my
function is a list of two objects (2 arrays). In my summary both objects should
be displayed but with a some introductory text like:

ls <- list(A="A123",B="B123")

summaryout=function(x,...){
	cat("This is output A:/n")
	x$A
	cat("This is output B:"/n")
	x$B
}

How can I achieve that both list-elements are displayed and the lines inbetween,
so that it looks nice?

As the single list elements are arrays (partly 5-dimensional) is there a nice
way to display them i a summary or print method?

cheers,


best regards,

Johannes

Hi Johannes,

You are on the right track. Just need to use the right line break
indicators, and explicitly call print. Like this:

tmp <- list(A="A123",B="B123")

summaryout=function(x,...){
       cat("This is output A:\n")
       print(x$A)
       cat("This is output B:\n")
       print(x$B)
}

summaryout(tmp)

Best,
Ista
