plotLongVector: A simple function to plot a very long vector.

In HilbertVis: Hilbert curve visualization

Description

This function does basically the same as just calling plot( vec ) but is much faster in case of a very long vector. This is because it first calls shrinkVector.

Usage

plotLongVector(vec, offset = 1, shrinkLength = 4000, xlab = "", ylab = "", ...)

Arguments

vec	The numerical vector to be plotted. May be an ordinary or an IRanges::Rle vector.
offset	The x axis is labelled with numbers from offset to offset+length(vec)-1.
shrinkLength	To which length to shrink the vector before plotting it. Should be at least the width of your plot in pixels.
xlab	The label of the x axis, to be passed to plot.
ylab	The label of the y axis, to be passed to plot.
...	Further arguments to be passed to plot.

Value

Invisible Null and a plot.
