 \title{Retrieve and set component labels, indices, and witness genes from IcaSet}
 \description{
   These generic functions access and set the attributes \code{compNames}, \code{indComp} and \code{witGenes}
    stored in an object of class \code{IcaSet}.
 }
 \usage{
 indComp(object)
 indComp(object) <- value
 compNames(object)
 compNames(object) <- value
 witGenes(object)
 witGenes(object) <- value
 }
 \arguments{
   \item{object}{object of class \code{IcaSet}}
   \item{value}{Numeric vector for \code{indComp}, character vector for \code{compNames} and
     \code{witGenes}, with length equal to \code{ncol(A(object))}
     and containing: component indices (for
     \code{indComp}), labels (for \code{compNames}), or gene witness IDs (for \code{witGenes}).}
 }
 
 \value{
   \code{indComp} returns a numeric vector containing  component indices;
   \code{compNames} returns a character vector containing component labels;
   \code{witGenes} returns a character vector containing  witness genes IDs.
