Coercion from SCE drops off rowData #81

That is a bit annoying. suppressPackageStartupMessages(library(SingleCellExperiment))
# Create dummy data
n_cells <- 100
n_genes <- 50
# Create a dummy SingleCellExperiment object
sce <- SingleCellExperiment(
assays = list(counts = matrix(rpois(n_cells * n_genes, lambda = 10), nrow = n_genes, ncol = n_cells)),
colData = DataFrame(
cell_id = paste0("cell", 1:n_cells),
condition = sample(c("control", "treatment"), n_cells, replace = TRUE)
),
rowData = DataFrame(
gene_id = paste0("gene", 1:n_genes),
gene_name = paste0("Gene_", 1:n_genes)
)
)

When SingleCellExperiment is converted into SummarizedExperiment, the resulting SE does not include rowData that was in the input,
