Mark specified values as missing — mark

Replaces all values in the peak table that equal the specified value with NA. For example, vendor software might use 0 or 1 to signal a missing value, which is not understood by R.

Usage

mark_nas(object, value, assay.type = NULL, name = NULL)

Arguments

object: a SummarizedExperiment object
value: the value to be converted to NA
assay.type: character, assay to be used in case of multiple assays
name: character, name of the resultant assay in case of multiple assays

Value

SummarizedExperiment object as the one supplied, with missing values correctly set to NA.

Examples

data(toy_notame_set)
nas_marked <- mark_nas(toy_notame_set, value = 0)
