Drawer of blank plot area

Description

Draws a blank plotting area for further handmade drawings.

Usage

blankplot(
  xlim = c(0, 1),
  ylim = c(0, 1),
  bty = "l",
  mgp = c(2.5, 1, 0),
  main = "",
  sub = "",
  xlab = "",
  ylab = "",
  ...
)

Arguments

xlim	A pair of numerics. The x limits of the plot.
ylim	A pair of numerics. The y limits of the plot.
bty	A character. The type of box of the plot passed to graphics::par().
mgp	A set of three numerics. The amounts of margin lines passed to graphics::par().
main	A string. The main title (by default a blank).
sub	A string. The sub title (by default a blank).
xlab	A string. The label for the x axis (by default a blank).
ylab	A string. The label for the y axis (by default a blank).
...	Other arguments passed to graphics::plot().

Details

R's built-in plotting functions such as graphics::plot(), graphics::boxplot() and graphics::hist() are so useful that your daily analysis and data visualization can be often completed by only these function. However, there are also times that you want to create more complicated graphs. In such cases, you will first construct a blank plotting are by graphics::plot(), and then further add required drawings. blankplot() can be used as a quick wrapper for this routine procedure. Just use it to create a tabula-rasa plotting region with designated x and y limits, from where your data visualization can start over.

Examples

n <- 100
r <- seq(0, 2 * pi, length.out = n)
x <- 16 * sin(r)^3
y <- 13 * cos(r) - 5 * cos(2 * r) -
  2 * cos(3 * r) - cos(4 * r)
blankplot(range(x), range(y))
col <- rainbow(n)
segments(x, y, x[1], y[1], col = col, lty = "22")
segments(x[-n], y[-n], x[-1], y[-1], col = col[-1])
