Description

Get or set the start, end, or width of an object.

NOTE: This man page is for the start, `start<-`, end, `end<-`, width, and `width<-` 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

Arguments

x

An object containing start, end, and width values.

...

Additional arguments, for use in specific methods.

value

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

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<-`
