+\usage{

+  nbOccInComp_simple(icaSet, params,

+    selectionByComp = NULL, level = c("features", "genes"))

+}

+\arguments{

+  \item{icaSet}{An object of class \code{\link{IcaSet}}.}

+

+  \item{params}{An object of class

+  \code{\link{MineICAParams}} containing the parameters of

+  the analysis. \code{cutoffSel(params)} is used as a

+  threshold on the absolute projections to select the

+  contributing features/genes.}

+

+  \item{selectionByComp}{The list of components already

+  restricted to the contributing features/genes (each

+  element is a vector of projection values indexed by

+  features or genes).}

+

+  \item{level}{The attribute of \code{icaSet} to be used,

+  the occurences of either the \code{"features"} (using

+  \code{S(icaSet)}) or the \code{"genes"} (using

+  \code{SByGene(icaSet)}) will be reported.}

+}

+\value{

+  Returns a data.frame whose columns are: \code{gene} the

+  feature or gene IDs, \code{nbOcc} the number of

+  components the gene contributes to, \code{components} the

+  indices of those components.

+}

+\description{

+  For each feature/gene, this function returns the indices

+  of the components they contribute to.
