Interaction with classes
Let's say we have an object called a_genome
from class BSgenome
. With a_genome
, you can ask questions like these:
# What is a_genome's main class?
class(a_genome) # "BSgenome"
# What is a_genome's other classes?
is(a_genome) # "BSgenome", "Annotated"
# Is a_genome an S4 representation?
isS4(a_genome) # TRUE
If you want to find out more about the a_genome
object, you can use the accessor show(a_genome)
or use other specific accessors from the list of .S4methods(class = "BSgenome")
.
