Description

Adds an axis-aligned box to an existing plot.

Usage

drawBox(x, fg = par('fg'), bg = NA,
        colCtr = NA, lty = par('lty'), lwd = par('lwd'),
        pch = par('pch'), cex = par('cex'))
# S3 method for list
drawBox(x, fg = par('fg'), bg = NA,
        colCtr = NA, lty = par('lty'), lwd = par('lwd'),
        pch = par('pch'), cex = par('cex'))
# S3 method for default
drawBox(x, fg = par('fg'), bg = NA,
        colCtr = NA, lty = par('lty'), lwd = par('lwd'),
        pch = par('pch'), cex = par('cex'))
