# segments {graphics}

### Description

Draw line segments between pairs of points.

### 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

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')
