When I try to install "MAST", the error occurred as follows and installation halted.
Could you help me to resolve this issue ?

I believe this is a consequence from this issue, in which case BiocManager::install(c("SingleCellExperiment", "MAST"), type = "source") should resolve it in the immediate. I may need to manually bump the version number to resolve this long-term.
