lines.segmented(segmented)
lines.segmented()所属R语言包：segmented
Bars for interval estimate of the breakpoints
条形区间估计的断点
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Draws bars relevant to breakpoint estimates (point estimate and confidence limits) on the current device
绘制条有关当前设备上设置断点，估计（点估计和置信区间）
用法----------Usage----------
## S3 method for class 'segmented'
lines(x, term, bottom = TRUE, shift=TRUE, conf.level = 0.95, k = 50,
pch = 18, rev.sgn = FALSE, ...)
参数----------Arguments----------
参数：x
an object of class segmented
一个对象的类segmented
参数：term
the segmented variable of the breakpoints being drawn. It may be unspecified when there is a single segmented variable
断点的分段变量被绘制。它可能是未指定时，有一个单一分段变量
参数：bottom
logical, indicating if the bars should be plotted at the bottom (TRUE) or at the top (FALSE)
逻辑，表示应绘制的底部（TRUE）还是在顶部如果条形（FALSE）
参数：shift
logical, indicating if the bars should be "shifted" on the y-axis before plotting. Useful for multiple breakpoints with overlapped confidence intervals
逻辑，指示如果条形应偏移之前，绘制在y-轴。有用的置信区间重叠的多个断点
参数：conf.level
the confidence level of the confidence intervals for the breakpoints
置信水平的置信区间为断点
参数：k
a positive integer regulating the vertical position of the drawn bars. See Details
调节拉伸杆的垂直位置的正整数。查看详细资料
参数：pch
either an integer specifying a symbol or a single character to be used in plotting the point estimates of the breakpoints. See points
一个整数，指定一个符号或一个单一的字符用于绘制的点估计的断点。见points
参数：rev.sgn
should the signs of the breakpoint estimates be changed before plotting? see Details
应该改变之前绘制的断点估计的迹象？查看详细资料
参数：...
further arguments passed to segments, for instance "col" that can be a vector.
进一步的参数传递给segments，例如关口，可以是一个向量。

详细信息----------Details----------
lines.segmented simply draws on the current device the point estimates and relevant confidence limits of the estimated breakpoints from a "segmented" object. The y coordinate where the bars are drawn is computed as usr[3]+h if bottom=TRUE or usr[4]-h when bottom=FALSE, where h=(usr[4]-usr[3])/abs(k) and usr are the extremes of the user coordinates of the plotting region. Therefore for larger values of k the bars are plotted on the edges. The argument rev.sgn allows to change the sign of the breakpoints before plotting. This may be useful when a null-right-slope constraint is set.
lines.segmented只是利用当前设备上的点估计和有关的置信区间的估计断点“分段”对象。绘制矩形条，y坐标的计算方法为usr[3]+h如果bottom=TRUE或usr[4]-hbottom=FALSE，其中h=(usr[4]-usr[3])/abs(k)和usr是极端用户坐标的绘图区域。因此，对于较大的值k杆的边缘上绘制。参数rev.sgn打印之前，可以改变符号的断点。这可能是有用的，当一个空的右坡度约束。
