Hello, Some weeks ago the experDesign package was released on CRAN: https://CRAN.R-project.org/package=experDesign The package helps designing experiments to avoid batch effects confounding the result by distributing the samples on batches according to their features. If you or your colleagues design this kind of analysis I hope experDesign will be useful. I greatly appreciate your feedback, especially if you find bugs (despite the testing) or think of any improvement. To all developers, maintainers and the CRAN team that made this possible: Thank you! Best regards, Llu?s GitHub: https://github.com/llrs/experDesign CRAN: https://CRAN.R-project.org/package=experDesign
