Display utilities
Description
Low-level utilities that control display of vector-like objects.
Usage
get_showHeadLines()
set_showHeadLines(n=5)
get_showTailLines()
set_showTailLines(n=5)
Arguments
n |
A non-negative integer that controls the number of vector elements to display. |
Details
For the sake of keeping display compact, the show() methods
for Vector derivatives only display 5 head and 5 tail vector
elements.
However, the number of head and tail elements to display can be changed
by setting global options showHeadLines and showTailLines
to the desired values.
get_showHeadLines(), set_showHeadLines(),
get_showTailLines(), and set_showTailLines() are
convenience functions for getting/setting these global options.
Value
get_showHeadLines() and get_showTailLines() return the
current showHeadLines and showTailLines values.
set_showHeadLines() and set_showTailLines() return the
showHeadLines and showTailLines values before the
change, invisibly.

library(IRanges)
ir <- IRanges(start=11:45, width=10)
ir # displays 5 head and 5 tail ranges
set_showHeadLines(18)
ir # displays 18 head ranges
set_showHeadLines() # back to default
