I appreciate these are now too late for buster, but the ITPs for these two packages have been open a while (#814736, #814741) and packaging has been delayed quite a while because irkernel wasn't on CRAN (see https://github.com/IRkernel/IRkernel/issues/438). This has recently been resolved, so these two packages should be ready to upload. https://salsa.debian.org/r-pkg-team/r-cran-irdisplay https://salsa.debian.org/r-pkg-team/r-cran-irkernel Gordon
