Subset an SingleAnnotation Object

Subset an SingleAnnotation Object

# S3 method for SingleAnnotation
[(x, i)

Arguments

x

An SingleAnnotation-class object.
i

A vector of indices.

Details

The SingleAnnotation class object is subsetable only if the containing AnnotationFunction-class object is subsetable. All the anno_* functions are subsetable, so if the SingleAnnotation object is constructed by one of these functions, it is also subsetable.

Examples

ha = SingleAnnotation(value = 1:10)
ha[1:5]
#> A single annotation with continuous color mapping
#>   name: anno1 
#>   position: column 
#>   show legend: TRUE 
#>   items: 5 
#>   color is randomly generated
#>   width: 1npc 
#>   height: 1*5mm 
#>   this object is  subsetable
#>   12.7686666666667mm extension on the right 
draw(ha[1:5], test = "ha[1:5]")
