Hello,
I have a library 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 library 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

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:

source("assayObjectDemo.R")
where assayObjectDemo.R is just:
setClass("assayObjectDemo",contains="assayObject")
createDemoAssayObject <- function() {
df <- data.frame()
assay<-new(Class="assayObjectDemo")
assay
}
I get:

:
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,

No you ***DO NOT***. You have a ***PACKAGE***. If you cannot even get
your terminology straight, what hope is there for you?
