Dear Hervé, dear maintainers We are bitten by the following issue related to SE and SCE:
Using version 1.38.0: ## BiocManager::install("Bioconductor/SummarizedExperiment", ## ref = "a320baea6278ba6d7e6c646f5576ea6e8b6cd732", ## force = TRUE) ## version 1.38.0 > suppressPackageStartupMessages(library("SummarizedExperiment")) > suppressPackageStartupMessages(library("SingleCellExperiment")) > packageVersion("SummarizedExperiment") [1] ‘1.38.0’ > example("SummarizedExperiment", echo = FALSE) > as(se0, "SingleCellExperiment") ## OK class: SingleCellExperiment dim: 200 6 metadata(0): assays(1): counts rownames: NULL rowData names(0): colnames(6): A B ... E F colData names(1): Treatment reducedDimNames(0): mainExpName: NULL altExpNames(0): But with the latest version: ## BiocManager::install("SummarizedExperiment", ## force = TRUE) ## version 1.38.1 > suppressPackageStartupMessages(library("SummarizedExperiment")) > suppressPackageStartupMessages(library("SingleCellExperiment")) > example("SummarizedExperiment", echo = FALSE) > packageVersion("SummarizedExperiment") [1] ‘1.38.1’ > as(se0, "SingleCellExperiment") ## Error Error in validObject(.Object) : invalid class “SingleCellExperiment” object: superclass "ExpData" not defined in the environment of the object's class Which can be recovered with (which was removed from 1.38.1): > setClassUnion("ExpData", c("matrix", "SummarizedExperiment")) > as(se0, "SingleCellExperiment") ## Error class: SingleCellExperiment dim: 200 6 metadata(0): assays(1): counts rownames: NULL rowData names(0): colnames(6): A B ... E F colData names(1): Treatment reducedDimNames(0): mainExpName: NULL altExpNames(0): Is this a matter of patience that will fix itself with another update?
