R: How can I pass a dataframe to an object?
I'm newbie in R and I'm creating objects but I don't know how to pass a dataframe to an object in the constructor. I have made a development but it doesn't work.
setClass("gComparativa", slots=list(data="dataframe"))
show <- function(object) 0
setGeneric("show")
setMethod("show", "gComparativa", function(object)
)
When I'm going to create the object with:
g <- new("gComparativa", data=dataValue)
I've got this error:
Warning message: undefined slot classes in definition of
"gComparativa": data(class "dataframe")
Is it possible to pass a dataframe to an object? How can I do that?

"dataframe"isn't an S3 class, perhaps you meant"data.frame"? Or maybe just"ANY"? If you're really new to R, S4 seems like an unpleasant place to start.

I have checked that I can pass data.frame with "ANY". Thank you!!!
