Hello,

How can I retrieve the source code of "isa.iterate()" function in package "isa2"?

I tried by typing isa.iterate, or getAnywhere(isa.iterate), or getMethods("isa.iterate", "list"). All failed.

Thanks.

Regards,

Jianhai

Hello,

Thanks for your reply. It is like the following, still no source code.

> isa2:::isa.iterate
standardGeneric for "isa.iterate" defined from package "isa2"

function (normed.data, ...)
standardGeneric("isa.iterate")
<environment: 0x1ffeb88>
Methods may be defined for arguments: normed.data
Use showMethods("isa.iterate") for currently available ones.

Since the generic is not exported, showMethods() needs to be told where to look

> showMethods("isa.iterate", where=getNamespace("isa2"))
Function: isa.iterate (package isa2)
normed.data="list"

A convenient way to get source code for methods when there are only one or two is to use the argument includeDefs=

> showMethods("isa.iterate", where=getNamespace("isa2"), includeDefs=TRUE)
Function: isa.iterate (package isa2)
normed.data="list"
function (normed.data, ...) 
isa.iterate.default(normed.data, ...)

leading finally to isa2:::isa.iterate.default.
