S4 inheritance and old class
Hey everyone, I would like to develop a package using S4 classes. I have to define several S4 classes that inherits from each others as follow: # A <- B <- C <- D I also would like to define .DollarNames methods for these class so, if I have understood well, I also have to define an old class as follow: # AOld <- A <- B <- C <- D setOldClass(Classes = "AOld") setClass( Class = "A", contains = "AOld", slots = list(A = "character") ) .Doll...

Autocompletion for the new S3 generic @ method?
...0("row", 1:10), paste("col", 1:2)), class="mm") m at row1 However, seems like currently it does not support autocompletion. Wouldn?t it make sense to add a method like .EtaNames() which would provide tab autocompletions for x@<tab> in the same way current .DollarNames() does for x$<tab>? Regards, Karolis K.

Rcpp, dyn.load and C++ problems
I would go to the source, in this case Dirk Eddelbuettel's (I hope I spelled it correctly) documentation for Rcpp: http://dirk.eddelbuettel.com/code/rcpp/Rcpp-attributes.pdf Note that you need to do sourceCpp("logistic_map.cpp") in R instead of building and dyn.load()-ing the object.

However search for "Rcpp calling C++ functions from R" gives a lot of result but I think some of them are outdated and others don't agree with each other. Can you point to a specific good on-line guide for me? Regards
