S4 setClass / initialize misunderstanding
Hi, I recently ran into this problem. I couldn't find any mention of it in
the setClass documentation.
setClass("Foo", representation(file = "character"))
setMethod("initialize", "Foo", function(.Object, file) {
print(file)
})
setClass("Bar", contains = "Foo")
And the error:

issue with compiling r6
...U
Options not enabled: memory profiling
make fails at:
byte-compiling 'methods'
initializing class and method definitions ...Error: .onLoad failed in
loadNamespace() for 'methods', details:
call: new("classRepresentation")
error: could not find function "isVirtualClass"
The only other oddity of my system/potential clue is that symbolic
links sometimes behave strangely because I am working on a VirtualBox
virtual machine with a virtual Linux filesystem layered over an HGFS
filesystem.

creating objects with a slot of class formula, using new
Hi,
This works fine.
>setClass("a",representation(b="list",c="list"))
>new("a",b=list(7))
>An object of class "a"
Slot "b":
[[1]]
[1] 7
Slot "c":
list()
But, now suppose you want a slot to accept an object of class formula...
>setClass("a",representation(b="list",c="formula"))
