译者:生物统计家园网 机器人LoveR
描述----------Description----------
adds one or more arrowheads to a plot; shape is either curved, a triangle, a circle or ellipse.
添加一个或多个箭头的图;弯曲形状,三角形,圆形或椭圆形。
用法----------Usage----------
Arrowhead(x0, y0, angle = 0, arr.length = 0.4,
arr.width = arr.length/2, arr.adj = 0.5,
arr.type = "curved", lcol = "black", lty = 1,
arr.col = lcol, arr.lwd = 2, npoint = 5)
参数----------Arguments----------
参数:x0
x-coordinates of points at which to draw arrowhead; either one value or a vector.
在要绘制箭头的点的x坐标的任一个值或一个矢量。
参数:y0
y-coordinates of points at which to draw arrowhead; either one value or a vector.
y坐标的点,在要绘制箭头;的任一个值或一个矢量。
参数:angle
angle of arrowhead (anti-clockwise, relative to x-axis), in degrees [0,360]; either one value or a vector.
箭头(反时针方向,相对x轴)的角度,以度为[0360]的任一个值或一个矢量。
参数:arr.length
approximate length of arrowhead, in cm; either one value or a vector.
近似长度的箭头,以厘米为一个值或一个矢量。
参数:arr.width
approximate width of arrowhead, in cm; either one value or a vector.
箭头,在近似宽度厘米;的任一个值或一个矢量。
参数:arr.adj
0,0.5,1 specifying the adjustment of the arrowhead.
0,0.5,1指定的箭头的调整。
参数:arr.type
type of arrowhead to draw, one of "curved","triangle","circle","ellipse".
类型的箭头画的“曲线”,“三角”,“圆”,“椭圆”。
参数:lcol
line color specifications; either one value or a vector.
线的颜色规格,任何一个值或一个向量。
参数:lty
line type specifications; either one value or a vector.
线路类型规格;任何一个值或一个向量。
参数:arr.col
color of arrowhead; either one value or a vector.
颜色的箭头;的任一个值或一个矢量。
参数:arr.lwd
line width of arrowhead.
直线宽度的箭头。
参数:npoint
only if arr.type = "curved": number of points to draw the curve; increase for smoother arrowheads
只有arr.type=“曲线”的绘制曲线的点的数量,增加流畅的箭头

详细信息----------Details----------
x0, y0, angle, arr.length, arr.width, lcol, lty and arr.col can be a vector, of the same length.
x0,y0,angle,arr.length,arr.width,lcol,lty和arr.col可以是一个向量,具有相同的长度。
if arr.adj = 0.5, then the centre of the arrowhead is at the point at which it is drawn.
如果arr.adj= 0.5,然后在箭头的中心,是在它被绘制在点。
arr.adj = 1 causes the tip of the arrowhead to touch the point.
arr.adj= 1导致的箭头的前端接触的点。
arr.adj = 0 causes the base of the arrowhead to touch the point.
arr.adj= 0时,箭头的基础上触摸的点。
The type of the arrowhead is set with arr.type which can take the values:
类型的箭头arr.type的值可以取:
"triangle": uses filled triangle
“三角”:使用实心三角形
"curved" : draws arrowhead with curved edges
“曲线”:绘制箭头弯曲的边缘
"circle" : draws circular head (where arr.width=arr.length)
“圈子”:绘制圆形头(其中arr.width = arr.length)
"ellipse" : draws ellipsoid head
“椭圆”:绘制椭球头
