In draw: Wrapper Functions for Producing Graphics

Description

Draws a line on the page given positioning, dimensions and styling.

Usage

drawLine(x, y, opacity = .pkgenv$lineOpacity, lineColor = .pkgenv$lineColor,
  lineWidth = .pkgenv$lineWidth, lineType = .pkgenv$lineType,
  arrowAngle = .pkgenv$arrowAngle, arrowLength = .pkgenv$arrowLength,
  arrowUnits = .pkgenv$arrowUnits, arrowEnds = .pkgenv$arrowEnds,
  arrowType = .pkgenv$arrowType, units = .pkgenv$units, ...)

Arguments

x	Numeric vector for the x-axis positions of the control points.
y	Numeric vector for the y-axis positions of the control points.
opacity	Numeric value for the transparency with values ranging from 0 (transparent) to 1 (non-transparent).
lineColor	Character value for the color of the lines.
lineWidth	Numeric value for the width of the lines.
lineType	Character value for the line type. One of "blank", "solid", "dashed", "dotted", "dotdash", "longdash", or "twodash" (see "lty" in par).
arrowAngle	Numeric value of the angle for arrows. Smaller numbers create narrower arrows, and larger numbers produce wider arrows.
arrowLength	Numeric value of the length for arrows.
arrowUnits	Character value of the measurement unit for arrows.
arrowEnds	Character value indicating which end to draw arrows on lines. Must be one of "last", "first" or "both".
arrowType	Character value indicating if the arrow heads should be closed or open. Must be one of "open" or "closed".
units	Character value for the unit to use when specifying measurements.
...	Additional arguments passed to grid.lines.

Value

A grid.lines grob object.
