...did write a (very rudimentary) symbolic solver for systems of polynomial equations in pure R. It should be able to solve this one. Please let me know if this is of interest and I will provide further details. ### Case (b) Again, it should be possible to solve, see some examples: https://github.com/discoleo/R/blob/master/Math/Systems.NLE.Tutorial.md https://github.com/discoleo/R/blob/master/Math/Systems.Lambert.R I did solve much more complex ones, for a monster see: https://github.com/discoleo/R/blob/master/Math/Poly.System.S5.Ht.Formulas.Derivation.HS0.R [and the remaining Poly.System.S5.Ht... scrip...

...-dependencies. Package pkgdepR may offer some of the functionality; but I did not have time to fully explore it: https://cran.r-project.org/web/packages/pkgdepR/index.html If such tools are not yet available, I have opened an issue on GitHub and would like to collect any ideas: https://github.com/discoleo/PackageBrowser/issues/1 There are some model packages that could be used to test the clustering: 1) Rcpp, xml: the core-functionality will always be needed; splitting into modules may not be possible/useful; 2) pracma: most reverse-dependencies are likely using only a small subset of the function...

...etc - the generating processes may differ). ### Harmonic Mean Did not encounter it often: maybe because of the problematic handling of 0. I do have in the meantime a nice workaround for 0 (which also works with the geometric mean), see also (unfortunately not well documented): https://github.com/discoleo/R/blob/master/Stat/Moments.Stat.R v0 = 1; # some initial "skew" 1 /(xharm + v0) = sum( 1 / (x + v0) ) / length(x) xgeom = prod(x + v0)^(1/length(x)) - v0; I apologize for the late reply; I did not have much time to read messages during the past weeks.

B # B.1.1.529 and branches do not have any of the defining mutations of B.1.1; I have uploaded the code on GitHub: https://github.com/discoleo/R/blob/master/Stat/Infx/Cov2.Variants.R 1.) Does anyone have a better picture of what is going on? The sub-variants should have cumulative mutations. This should be the logic for the sub-lineages and I deduce it also by the data/post on the GitHub pango page: https://github.com/cov-lineages/pang...

...c shapes. It should offer researchers in the field of biological and chemical sciences a tool to easily generate diagrams depicting the studied biological processes. The package lacks a proper documentation and is not yet released on CRAN. However, it is available on GitHub: https://github.com/discoleo/BioShapes Although there are 27 unique cloners on GitHub, I am still looking for contributors and collaborators. I would appreciate any collaborations to develop it further. I can be contacted both by email and on GitHub. B.) Documentation Tools Is there a succinct, but sufficiently informati...

Dear Richard, I wrote s small shiny app to improve the search for CRAN-packages. It can be installed from GitHub: https://github.com/discoleo/PackageBrowser Searching for "(?<![- ]cat)astro|sun" yields 19 packages. A few (2 or 3) are unrelated. The remaining may be interesting, e.g. suntools, suncalc, astroFns. Sincerely, Leonard [[alternative HTML version deleted]]
