Just a few words... I usually cite softwares, especially if they are opensource (and encourage everyone to do so). Of course I would not append references for rkward or kile to my bib (neither word or excel).
While the response of the researcher using your software is not convincing, you can easily check if it is the journal's deliberate policy to exclude software references - e.g. to save space - or it was simply the author's ignorance why your package was not cited. The latter case seems to be more likely though. In defense of the 'ignorant' author, it should be noted that it is not always clear how to cite a software. For example, neither typing citation(tweedie), nor browsing through tweedie's documentation tells me how to cite it (of course, as a last resort I can mail the author of the package). Probably I would not be so helpless if we were in the same research field though. Related to this, can offer some explanation how to figure out the citations of packages in publications? best wishes, gabor Appendix: The sections below are straight from R console. > citation() To cite R in publications use: R Development Core Team (2008).
