I have a question regarding the build of my project papeR (hosted on
R-forge http://r-forge.r-project.org/R/?group_id=1574) with respect to
lme4.
Both, Windows and MacOS are complaining that lme4 doesn't export summary:
Error : object 'summary' is not exported by 'namespace:lme4'
ERROR: lazy loading failed for package 'papeR'
Linux however builds the project as desired.
I now did check my package using Uwe Ligges' winbuilder project and got
positive results i.e. no errors for Windows there. See (for the next 72
hours):
http://win-builder.r-project.org/y3uwwx93nJ92
http://win-builder.r-project.org/10mtpspKx7us
Can anyone tell me why this happens (only on R-forge and only for
certain systems) and how to prevent this?
[I already asked the R-forge maintainers and was redirected to the
general R mailing lists]
As a side note: The reason for importing lme4's summary is that
otherwise my function summary.fixef, which extracts fixed effects from
nlme and lme4 models for printing e.g. in reports, doesn't use/find
summary.mer on "mer" objects -- even if lme4 is loaded earlier. On the
other hand, lme models (from package nlme) are handled correctly despite
the fact that I do not import the corresponding summary function.
Thank you very much
Benjamin
