trace_value: Draw Paths to Points perpendicular to Coordinate Axis

In lfstat: Calculation of Low Flow Statistics for Daily Stream Flow Data

Description

To depict the distances in x and y direction to a point, draw lines and labels.

Usage

trace_value(x, y, digits = 0, annotate = TRUE, lab.x = x, lab.y = y, prefix = "",
            suffix = "", cex = 0.75, col = "blue", lty = 2, ...)

Arguments

x	numeric vector of x coordinates
y	numeric vector of y coordinates
digits	vector of length one or two, giving the number of digits used for rounding the label of the x and y coordinate.
annotate	logical, should the lines get annotated with labels?
lab.x	character vector of length one. Label of the x coordinate.
lab.y	character vector of length one. Label of the y coordinate.
prefix	vector of length one or two, text printed before the label of the x and y coordinate.
suffix	vector of length one or two, text printed after the label of the x and y coordinate.
cex	character expansion factor
col	color used for text and lines
lty	line type
...	other graphical parameters, passed on to lines, points and text.

Details

This function is vectorised over x and y.

Examples

x <- c(-2, 3)
curve(sin, -2*pi, 2*pi, xname = "t")
trace_value(x, sin(x), digits = c(0, 1))
