In tnaake/MatrixQCvis: Shiny-based interactive data-quality exploration for omics data

Return the number of a category

Description

hist_sample_num returns the number of a category (e.g. sample types) as a tbl. The function will retrieve first the column category in colData(se). The function will return a tbl containing the numerical values of the quantities.

Usage

hist_sample_num(se, category = "type")

Arguments

se	SummarizedExperiment object
category	character, corresponding to a column in colData(se)

Value

tbl

Examples

## create se
a <- matrix(seq_len(100), nrow = 10, ncol = 10, 
    dimnames = list(seq_len(10), paste("sample", seq_len(10))))
a[c(1, 5, 8), seq_len(5)] <- NA
set.seed(1)
a <- a + rnorm(100)
cD <- data.frame(name = colnames(a), type = c(rep("1", 4), rep("2", 6)))
rD <- data.frame(spectra = rownames(a))
se <- SummarizedExperiment::SummarizedExperiment(assay = a, 
    rowData = rD, colData = cD)

hist_sample_num(se, category = "type")
