SingleCellExperiment and SummarizedExperiment

这里的两个是不一样的

创建SummarizedExperiment

nrows <- 200; ncols <- 6
counts <- matrix(runif(nrows * ncols, 1, 1e4), nrows)
colData <- DataFrame(Treatment=rep(c("ChIP", "Input"), 3),
                     row.names=LETTERS[1:6])
se0 <- SummarizedExperiment(assays=SimpleList(counts=counts),
                            colData=colData)

结果如下

创建SingleCellExperiment

https://bioconductor.org/books/3.14/OSCA.intro/the-singlecellexperiment-class.html

结果如下

counts_matrix <- data.frame(cell_1 = rpois(10, 10), 
                    cell_2 = rpois(10, 10), 
                    cell_3 = rpois(10, 30))
rownames(counts_matrix) <- paste0("gene_", 1:10)
counts_matrix <- as.matrix(counts_matrix) # must be a matrix object!
sce <- SingleCellExperiment(assays = list(counts = counts_matrix))
sce
