Draws bars relevant to breakpoint estimates (point estimate and confidence limits)
 on the current device

lines.stepmented

Fitting regression models where, in addition to possible linear terms, one or more covariates have segmented (i.e., broken-line or piece-wise linear) or stepmented (i.e. piece-wise constant) effects. Multiple breakpoints for the same variable are allowed.
The estimation method is discussed in Muggeo (2003, <doi:10.1002/sim.1545>) and
illustrated in Muggeo (2008, <https://www.r-project.org/doc/Rnews/Rnews_2008-1.pdf>). An approach for hypothesis testing is presented
in Muggeo (2016, <doi:10.1080/00949655.2016.1149855>), and interval estimation for the breakpoint is discussed in Muggeo (2017, <doi:10.1111/anzs.12200>).
Segmented mixed models, i.e. random effects in the change point, are discussed in Muggeo (2014, <doi:10.1177/1471082X13504721>).
Estimation of piecewise-constant relationships and changepoints (mean-shift models) is
discussed in Fasola et al. (2018, <doi:10.1007/s00180-017-0740-4>).

Bars for interval estimate of the breakpoints — lines.stepmented

<dl>

 <dt>x</dt>
<dd>an object of class <code>stepmented</code>.</dd>

 <dt>term</dt>
<dd>the stepmented variable of the breakpoints being drawn. It may be unspecified when there is a single stepmented variable.</dd>

 <dt>bottom</dt>
<dd>logical, indicating if the bars should be plotted at the bottom (<code>TRUE</code>) or at the top (<code>FALSE</code>).</dd>

 <dt>shift</dt>
<dd>logical, indicating if the bars should be `shifted' on the y-axis before plotting. Useful for multiple breakpoints
 with overlapped confidence intervals.</dd>

 <dt>conf.level</dt>
<dd>the confidence level of the confidence intervals for the breakpoints.</dd>

 <dt>k</dt>
<dd>a positive integer regulating the vertical position of the drawn bars. See Details.</dd>

 <dt>pch</dt>
<dd>either an integer specifying a symbol or a single character to be used
 in plotting the point estimates of the breakpoints. See <code><a href='https://rdrr.io/r/graphics/points.html'>points</a></code>.</dd>

 <dt>.vcov</dt>
<dd>The full covariance matrix of estimates. If unspecified (i.e. <code>NULL</code>), the covariance matrix is computed internally by <code>vcov(x)</code>.</dd>

 <dt>.coef</dt>
<dd>The regression parameter estimates. If unspecified (i.e. <code>NULL</code>), it is computed internally by <code>coef(x)</code>.</dd>

 <dt>...</dt>
<dd>further arguments passed to <code><a href='https://rdrr.io/r/graphics/arrows.html'>arrows</a></code>, for instance `col' that 
 can be a vector.</dd>
