freq {MAST} | R Documentation

## Summary statistics for genes in an experiment

### Description

`freq` returns the frequency of expression, i.e., the proportion of non-zero values in `sc`. NAs can be optionally removed

### Usage

    freq(sc, na.rm = TRUE)

    condmean(sc)

    condSd(sc)

    numexp(sc)

### Arguments

`sc` | SingleCellAssay
`na.rm` | should NAs be removed, or carried through?

### Value

vector of proportions

### Functions

- `condmean`: Report the mean non-zero expression value for each gene. NAs are always removed.

- `condSd`: Report standard deviation of expression, for positive et for each gene. NAs are always removed.

- `numexp`: Report number of expressing cells ($>0$) per gene. NAs are removed.

### Examples

    data(vbetaFA)
    freq(vbetaFA)
    condmean(vbetaFA)
