[R] 'R CMD check' fails with "evaluation nested too deeply: infinite recursion"

[Joerg van den Hoff]

I get the error

Error : evaluation nested too deeply: infinite recursion / options(expressions=)?

during a 'R CMD check ...'

on one of my packages. The reason seems to be that this package is
mutually dependent on another one (i.e. the DESCRIPTION files of package
A lists package B under "Depends" and vice versa). this might be bad
design (having bits in both packages needed by the other), but I believe
prior to R 2.9. this did not cause trouble. now the log file of the
'check' is something like



Installing *source* package 'roiutils' ...
** R
** exec
** preparing package for lazy loading
Loading required package: roiutils
Loading required package: fzrutils
=======================CUT (many more of the same) ========================
Loading required package: roiutils
Loading required package: fzrutils
Loading required package: roiutils
Error : evaluation nested too deeply: infinite recursion / options(expressions=)?




i.e. it seems that R loads both packages again and again.

what am I missing/doing wrong?

thanks in advance
