segments

From graphics v3.0.3 by R-core R-core@R-project.org

Add Line Segments to a Plot

Draw line segments between pairs of points.

Keywords: aplot

Usage

segments(x0, y0, x1 = x0, y1 = y0, col = par("fg"), lty = par("lty"), lwd = par("lwd"), ...)

Arguments

x0, y0: coordinates of points from which to draw.
x1, y1: coordinates of points to which to draw. At least one must be supplied.
col, lty, lwd: graphical parameters as in par, possibly vectors. NA values in col cause the segment to be omitted.
...: further graphical parameters (from par), such as xpd and the line characteristics lend, ljoin and lmitre.

Details

For each i, a line segment is drawn between the point (x0[i], y0[i]) and the point (x1[i], y1[i]). The coordinate vectors will be recycled to the length of the longest.

The graphical parameters col, lty and lwd can be vectors of length greater than one and will be recycled if necessary.

Examples

library(graphics)

x <- stats::runif(12); y <- stats::rnorm(12)
i <- order(x, y); x <- x[i]; y <- y[i]
plot(x, y, main = "arrows(.) and segments(.)")
## draw arrows from point to point :
s <- seq(length(x)-1)  # one shorter than data
arrows(x[s], y[s], x[s+1], y[s+1], col= 1:3)
s <- s[-length(s)]
segments(x[s], y[s], x[s+2], y[s+2], col= 'pink')
