Nearest neighbour imputation

Description

Wrapper function for imputation methods based on nearest neighbour clustering. Currently llsImpute only.

Usage

nni(object, method=c("llsImpute"), subset=numeric(),...)

Arguments

object Numerical matrix with (or an object coercible to such) with samples in rows and variables as columns. Also takes exprSet in which case the transposed exprs slot is used.
subset For convenience one can pass a large matrix but only use the variable specified as subset. Can be colnames or indices.
method Currently "llsImpute" only.
... Further arguments to the chosen method.

Details

This method is wrapper function to llsImpute, See documentation for link{llsImpute} Extra arguments usually given to this function include:

Value

A clusterRes object. Or a list containing a clusterRes object as first and an exprSet object as second entry if the input was of type exprSet.
