  plotTargetAnnotation(x,precedence=TRUE,col=rainbow(length(x@annotation)),
    ...)

Arguments

x

an annotationByFeature or an annotationByGenicParts object

precedence

TRUE|FALSE. If TRUE there will be a hierachy of annotation features when calculating numbers (with promoter>exon>intron precedence). This option is only valid when x is a annotationByGenicParts object

col

a vector of colors for piechart or the bar plot
