getTargetAnnotationStats(x,percentage=TRUE,precedence=TRUE)

## S4 method for signature 'AnnotationByFeature'
getTargetAnnotationStats(x, percentage = TRUE,
  precedence = TRUE)

Arguments

x

a AnnotationByFeature object

percentage

TRUE|FALSE. If TRUE percentage of target features will be returned. If FALSE, number of target features will be returned

precedence

TRUE|FALSE. If TRUE there will be a hierachy of annotation features when calculating numbers (with promoter>exon>intron precedence)

That means if a feature overlaps with a promoter it will be counted as promoter overlapping only, or if it is overlapping with a an exon but not a promoter, #' it will be counted as exon overlapping only whether or not it overlaps with an intron.

Value

a vector of percentages or counts showing quantity of target features overlapping with annotation
