## Create tibble containing number of measured/missing features of samples

### Description

'samples_memi' returns a 'tbl' with the number of measured/missing features of samples. The function will take as input a 'SummarizedExperiment' object and will access its 'assay()' slot

### Usage

    samples_memi(se)

### Arguments

`se` | 'SummarizedExperiment' object

### Value

'tbl' with number of measured/missing features per sample

### Examples

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

    ## create the data.frame with information on number of measured/missing
    ## values
    samples_memi(se)
