lnormeS: Function to apply lowess normalization to an expression set.

Description

Like lnorm, but applies to and returns an ExpressionSet or AffyBatch object instead of a matrix.

Usage

lnormeS(eS, span=0.1)

Arguments

eS

An ExpressionSet or AffyBatch object

span

Smoothing parameter for lowess. Larger values correspond to more smoothness.

Value

Returns an ExpressionSet with exprs(eS) normalized by lnorm.
