Description Details Constructor Accessors Coercion Subsetting Looping and functional programming Displaying See Also Examples

The (non-virtual) SimpleList class extends the List virtual class.

The SimpleList class is the simplest, most generic concrete implementation of the List abstraction. It provides an implementation that subclasses can easily extend.

In a SimpleList object the list elements are stored internally in an ordinary list.

See the List man page for a quick overview of how to construct List objects in general.

The following constructor is provided for SimpleList objects:

: SimpleList(...): Takes possibly named objects as elements for the new SimpleList object.

Same as for List objects. See the List man page for more information.

All the coercions documented in the List man page apply to SimpleList objects.

Same as for List objects. See the List man page for more information.

Same as for List objects. See ?`List-utils` for more information.

When a SimpleList object is displayed, the "Simple" prefix is removed from the real class name of the object. See classNameForDisplay for more information about this.

List objects for the parent class.
The CompressedList class defined in the IRanges package for a more efficient alternative to SimpleList.
The SimpleIntegerList class defined in the IRanges package for a SimpleList subclass example.
The DataFrame class for another SimpleList subclass example.

## Displaying a SimpleList object:
x1 <- SimpleList(a=letters, i=Rle(22:20, 4:2))
class(x1)

## The "Simple" prefix is removed from the real class name of the
## object:
x1

library(IRanges)
x2 <- IntegerList(11:12, integer(0), 3:-2, compress=FALSE)
class(x2)

## The "Simple" prefix is removed from the real class name of the
## object:
x2

## This is controlled by internal helper classNameForDisplay():
classNameForDisplay(x2)
