Subset an AnnotationFunction Object

Subset an AnnotationFunction Object

# S3 method for AnnotationFunction
[(x, i)

Arguments

x	An AnnotationFunction-class object.
i	A vector of indices.

Details

One good thing for designing the AnnotationFunction-class is it can be subsetted, and this is the base for the splitting of the annotations.

Examples

anno = anno_simple(1:10)
anno[1:5]
#> An AnnotationFunction object
#>   function: anno_simple()
#>   position: column 
#>   items: 5 
#>   width: 1npc 
#>   height: 1*5mm 
#>   imported variable: pt_size, border, value, color_mapping, gp, pt_gp, pch 
#>   subsetable variable: value 
#>   this object is subsetable
draw(anno[1:5], test = "subset of column annotation")
