Our R package bioimagetools is on CRAN now. The package depends on EBImage, which is an Bioconductor package. The problem is, installing from CRAN via
install.packages("bioimagetools") will only install dependencies from CRAN, not from Bioconductor (also Bioconductor is considered a „mainstream repository“). Some googling showed that I am not the only one with this issue. So here is the solution: In the DESCRIPTON file, add the line
Additional_repositories: https://bioconductor.org/packages/3.3/bioc/ The „Additional_repositories“ field was new to me.
