odfWeave is an R-package that is used for making dynamic reports by Sweave processing of Open Document Format (ODF) files. For anyone new to report generation and lacking knowledge of markup languages this might be a good starting point or even a true alternative to sweave / LATEX and others.
Now, anyone who recently tried to install the required zipping program for odfWeave might have noticed that there are currently no info-zip executables available (zip and unzip by info-zip software are suggested in the odfWeave manual). There are several other free zipping programs – but if you use these the default syntax for odfWeave changes. Looking into the internals it is revealed that the OS command specified for running the zipping program has to be adapted. There are some postings on the R-help mailing list concerning these topic, but none of them worked for me. After some trial and error I managed to get around this problem by using 7-zip with an adapted syntax and will share this here:
