plotfunctions (version 1.4)

getFigCoords: Get the figure region as coordinates of the current plot region, or as corrdinates of the figure region.

Description

Get the figure region as coordinates of the current plot region, or as corrdinates of the figure region.

Usage

getFigCoords(input = "f")

Arguments

input

Text string: 'f' (figure, default), 'p' (plot region), 'hf' (half way figure region), or 'hp' (half way plot region)

Value

A vector of the form c(x1, x2, y1, y2) giving the boundaries of the figure region as coordinates of the current plot region.

Examples

# NOT RUN {

fc <- getFigCoords()
pc <- getFigCoords('p')

    y0=pc[c(3,3,4,4)], y1=fc[c(3,3,4,4)], xpd=TRUE)

# Same plot with different axis:
emptyPlot(c(250,500),c(331, 336), bty='o')
fc <- getFigCoords()
pc <- getFigCoords('p')
arrows(x0=pc[c(1,2,1,2)], x1=fc[c(1,2,1,2)],
    y0=pc[c(3,3,4,4)], y1=fc[c(3,3,4,4)], xpd=TRUE)
hc <-  getFigCoords('h')

abline(h=getFigCoords('hf')[2], col='blue', xpd=TRUE)
# 2. center of plot region:
