Hi All,
I am working on a package BondLab for the analysis of fixed income securities.
Building the package results in the following:
Error in loadNamespace(package, c(which.lib.loc, lib.loc)) :
cyclic namespace dependency detected when loading ‘BondLab’, already loading
‘BondLab’
It occurs when I set the generic for the function mortgagecashflow. Further if
a function uses mortgagecashflow, similarly its generic, when set, causes the
above error. Other generics do not throw this error so I am quite sure it is
mortgagecashflow. The package and the code can be found on github.

I have been trying to figure this out for a couple of months to no avail. If
anyone has familiarity with this issue I would certainly appreciate any help
with the issue.
Hi Glenn --
The root of the problem is that you are defining both a generic and a
plain-old-function named MortgageCashFlow -- one or the other and you're fine.
R CMD INSTALL pkgA, where pkgA contains a single R file R/test.R
setGeneric("foo", function(x, ...) standardGeneric("foo"))
foo <- function(x, ...) {}
also generates this; maybe you meant something like
.foo <- function(x, ...) {}
setGeneric("foo", function(x, ...) standardGeneric("foo"),
useAsDefault=".foo")
or simply reversing the order of the declarations
foo <- function(x, ...) {}
setGeneric("foo", function(x, ...) standardGeneric("foo"))
?

Thanks,
