wrapper.impute.mle R Documentation
Imputation of peptides having no values in a biological condition.
Description
This method is a wrapper to the function impute.mle() of the
package imp4p adapted to an object of class MSnSet.
It does not impute MEC missing values.
Usage
wrapper.impute.mle(obj)
Arguments
obj
An object of class MSnSet.
Value
The Biobase::exprs(obj) matrix with imputed values instead
of missing
values.

Examples
utils::data(Exp1_R25_pept, package = "DAPARdata")
obj <- Exp1_R25_pept[seq_len(10), ]
level <- 'peptide'
metacell.mask <- match.metacell(GetMetacell(obj), c("Missing POV", "Missing MEC"), level)
indices <- GetIndices_WholeMatrix(metacell.mask, op = ">=", th = 1)
obj.imp.na <- wrapper.impute.mle(obj)
