Thank you for pointing this out. I had no idea about the distinction but there are some good references on the matter (http://www.r-bloggers.com/packages-v-libraries-in-r/). I am pasting the corrected version below, any suggestions appreciated:
I have a package that I created that defines a parent class, assayObject. I created other classes that inherit from it, say assayObjectDemo. Each one of those classes I wanted to make in its own directory separate from where the assayObject is defined (there are reasons for that). But now if I do: library(assayObject) #<--- where parent object is defined source("assayObjectDemo.R") where assayObjectDemo.R is just: setClass("assayObjectDemo",contains="assayObject") createDemoAssayObject <- function() { df <- data.frame() assay<-new(Class="assayObjectDemo") assay } I get: Error in reconcilePropertiesAndPrototype(name, slots, prototype, superClasses, : no definition was found for superclass “assayObject” in the specification of class “assayObjectDemo” What can I do? There are several reasons why I DO NOT want to define assayObjectDemo in the same package as assayObject, but I am not sure what the issue is here. If I step through the code in an ESS R session it works fine. Thanks in advance, Ramiro ________________________________________ From: Rolf Turner [r.tur...@auckland.ac.nz] Sent: Monday, February 23, 2015 3:41 PM To: Ramiro Barrantes; r-help@r-project.org Subject: Re: [R] Not finding superclass in library On 24/02/15 09:35, Ramiro Barrantes wrote: > Hello, > > I have a library that I created ..... <SNIP> No you ***DO NOT***.
