Thanks so much for your help. I am realizing that I may be over-complicating things for myself. I have learned a ton about creating methods, but I feel like I am trying to reinvent the data.frame class. Basically, I am trying to create a data.frame type object where I can enforce the header names

Re: [R] using setMethod or setGeneric to change S4 accessor symbol from @ to $

Thanks. Used getGeneric("[") to figure out the general format for the setMethod, but am having some problem with how to set up the actual function: > getGeneric("[") standardGeneric for "[" defined from package "base" function (x, i, j, ..., drop = TRUE) standardGeneric("[", .Primitive("[")) Me

Worked like a charm!! Thank you so much. I just plugged the following into my code ... setMethod("$", "CADresponses", function(x, name) slot(x, name)) ... and it worked perfect. If you don't mind, I have a quick follow up question, using your example setClass("A", representation(a="numeric",

[R] using setMethod or setGeneric to change S4 accessor symbol from @ to $

I created some S4 objects that are essentially data frame objects. The S4 object definitions were necessary to verify data integrity and force a standardized data format. I am, however, finding myself redefining all the typical generic functions so that I can still manipulate my S4 objects as if
