asExprSet {pcaMethods} | R Documentation

## Convert pcaRes object to an expression set

### Description

This function can be used to conveniently replace the expression matrix in an `ExpressionSet` with the completed data from a `pcaRes` object.

### Usage

    asExprSet(object, exprSet)

### Arguments

`object` | `pcaRes` – The object containing the completed data.
`exprSet` | `ExpressionSet` – The object passed on to `pca` for missing value estimation.

### Details

This is not a standard `as` function as `pcaRes` object alone not can be converted to an `ExpressionSet` (the `pcaRes` object does not hold any `phenoData` for example).

### Value

An object without missing values of class `ExpressionSet`.
