Hello, I have been trying bioconda for R-tool dependencies for few of packages It is work perfectly but one of my tool need rentrez package (I've tried entrez-direct but I think It is something bit different). What should I do in that case? I've normally use this website for dependency https://bioconda.github.io/recipes
you could try to contribute your own conda package. We have written some documentation here: https://bioconda.github.io/contributing.html
For normal cran R packages have a look at https://bioconda.github.io/guidelines.html#r-cran. Hope that gets you started!
