Thank you. What you write above seems all reasonable (and as a poster who is able to attach 3 different plain text files, named logically (i.e. without calling them <foo>.txt), I pre-judge your programming abilities to be quite high !) I'll look at the cases etc and will use your proposals. (The only question for now: why did you not take the extra step and ask for R-bugs registration and do a regular bug report -> https://www.r-project.org/bugs.html ) Thanks again, Martin Maechler ETH Zurich and R Core Team > Please CC me on replies as I am not subscribed to the mailing list. > With best regards, > Jan Hauffa > x[DELETED ATTACHMENT external: aov.diff, plain text] > x[DELETED ATTACHMENT external: aov-error.txt, plain text] > x[DELETED ATTACHMENT external: aov-testcase.R, plain text] > ______________________________________________ > R-devel@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-devel ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
