start

The start(), end(), width(), and pos() generic getters and setters


Description

Get or set the start, end, width, or single positions stored in an object.

NOTE: This man page is for the start, `start<-`, end, `end<-`, width, `width<-`, and pos S4 generic functions defined in the BiocGenerics package. See ?stats::start for the start and end S3 generics defined in the stats package.

Usage

start(x, ...)
start(x, ...) <- value

end(x, ...)
end(x, ...) <- value

width(x)
width(x, ...) <- value

pos(x)

Arguments

x

For the start(), end(), and width() getters/setters: an object containing start, end, and width values.

For the pos{} getter: an object containing single positions.

...

Additional arguments, for use in specific methods.

value

The start, end, or width values to set on x.

Value

See specific methods defined in Bioconductor packages.

Examples

## start() getter:
start
showMethods("start")

library(IRanges)
showMethods("start")
selectMethod("start", "IRanges")  # start() getter for IRanges objects

## start() setter:
`start<-`
showMethods("start<-")
selectMethod("start<-", "IRanges")  # start() setter for IRanges objects

## end() getter:
end
showMethods("end")
selectMethod("end", "IRanges")  # end() getter for IRanges objects

## end() setter:
`end<-`
showMethods("end<-")
selectMethod("end<-", "IRanges")  # end() setter for IRanges objects

## width() getter:
width
showMethods("width")
selectMethod("width", "IRanges")  # width() getter for IRanges objects

## width() setter:
`width<-`
showMethods("width<-")
selectMethod("width<-", "IRanges")  # width() setter for IRanges objects

## pos() getter:
pos
showMethods("pos")
selectMethod("pos", "UnstitchedIPos")  # pos() getter for UnstitchedIPos
                                       # objects
