IntegerRangesList-class {IRanges} | R Documentation |
The IntegerRangesList virtual class is a general container for storing a list of IntegerRanges objects.
In the code snippets below, x
is a IntegerRangesList
object.
All of these accessors collapse over the spaces:
start(x), start(x) <- value
: Get or set the starts of the
ranges. When setting the starts, value
can be an integer vector
of length sum(elementNROWS(x))
or an IntegerList object of
length length(x)
and names names(x)
.
end(x), end(x) <- value
: Get or set the ends of the
ranges. When setting the ends, value
can be an integer vector
of length sum(elementNROWS(x))
or an IntegerList object of
length length(x)
and names names(x)
.
width(x), width(x) <- value
: Get or set the widths of the
ranges. When setting the widths, value
can be an integer vector
of length sum(elementNROWS(x))
or an IntegerList object of
length length(x)
and names names(x)
.
space(x)
: Gets the spaces of the ranges as a
character vector. This is equivalent to names(x)
, except each
name is repeated according to the length of its element.
In the code snippet below, x
is an IntegerRangesList
object.
as.data.frame(x, row.names = NULL, optional = FALSE,
..., value.name = "value", use.outer.mcols = FALSE,
group_name.as.factor = FALSE)
:
Coerces x
to a data.frame
. See as.data.frame on the
List
man page for details (?List
).
In the following code snippet, from
is something other than a
IntegerRangesList
:
as(from, "IntegerRangesList")
: When from
is a
IntegerRanges
, analogous to as.list
on a vector.
Any arithmetic operation, such as x + y
, x * y
, etc,
where x
is a IntegerRangesList
, is performed identically on
each element. Currently, IntegerRanges
supports only the *
operator, which zooms the ranges by a numeric factor.
