plotTargetAnnotation {genomation} | R Documentation |
This function plots a pie or bar chart for showing percentages of targets annotated by genic parts or other query features
plotTargetAnnotation(x, precedence = TRUE, col = getColors(length(x@annotation)), cex.legend = 1, ...) ## S4 method for signature 'AnnotationByFeature' plotTargetAnnotation(x, precedence = TRUE, col = getColors(length(x@annotation)), cex.legend = 1, ...)
x |
a |
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

col |
a vector of colors for piechart or the bar plot |
cex.legend |
a numeric value of length 1 to specify the size of the legend. By default 1. |
