infobar: Draws rectangles with text in them

In StratigrapheR: Integrated Stratigraphy

Draws rectangles with text in them

Description

Draws rectangles with text in them, typically to delimit (stratigraphical) intervals (e.g. magnotochrons, but also lithostratigraphy,...)

Usage

infobar(
  xmin,
  xmax,
  ymax,
  ymin,
  labels = NA,
  m = list(),
  t = list(),
  srt = 90,
  family = par("family"),
  xpd = par("xpd")
)

Arguments

xmin, xmax, ymin, ymax	x and y limits for the rectangles. You can either provide 1 or n of each (if you want to have always the same x limits but multiple and different y ones it is possible)
labels	a 1 or n character vector (i.e. text) specifying the text to be written in the rectangle. You can write "" for no text.
m, t	a list graphical parameters (of length 1 or n) to feed multigons() for m and to text() for t. See respective help pages ?multigons and ?text for the possible arguments. See the example for illustration, and ?merge_list for further information.
srt, family, xpd	further graphical parameters, see ?par for information

Examples

labels <- c("High 5", "Low 5", "5")
ymin <- c(10,-10,2.5)
ymax <- c(20,0, 7.5)

plot(c(0,6),c(-20,20), type = "n")

infobar(xmin = 0, xmax = 1, ymin = ymin, ymax = ymax, labels,
        m = list(col = c("grey","grey", "red"),
                 border = "black", density = 10),
        t = list(cex = 1.5, col = "white"))
