## Normalization by loess method

### Description

Apply loess normalization to data

### Usage

    normLoess(dataMatrix, plateRows, plateCols, dataRows = NULL,
      dataCols = NULL)

### Arguments

`dataMatrix` | Data frame or numeric matrix. Columns are plates, and rows are plate wells.
`plateRows, plateCols` | Number of rows/columns in plate.
`dataRows, dataCols` | Optional integer vector. Indicate which row/column numbers from the dataMatrix should be normalized. If NULL then all rows/columns from the dataMatrix are used.

### Details

Loess normalization adjusts each well by the fitted row and column values generated by calculating the loess curve for each row and column.

### Value

Numeric matrix of normalized data in the same format as dataMatrix

### Note

For information on how to arrange your dataset for dataMatrix, please see (`ex_dataMatrix`)
