描述----------Description----------
Performs a fast segmentation algorithm based on the cyber t test and the t statistics.
执行快速分割算法，基于网络的t检验和t统计。
用法----------Usage----------
segment(x, alpha = 0.05, segMedianT = 0, minSeg = 3,
eps = 0, delta = 20, maxInt = 40, squashing = 0,
cyberWeight = 50, segPlot = TRUE, ...)
参数----------Arguments----------
参数：x
Values to be segmented.
值分割。
参数：alpha
Real value between 0 and 1 is interpreted as the percentage of total points that are considered as initial breakpoints. An integer greater than 1 is interpreted as number of initial breakpoints. Default = 0.05.
百分比总积分作为初始断点认为被解释为0和1之间的真正价值。一个大于1的整数被解释为初始断点数目。默认值= 0.05。
参数：segMedianT
Vector of length 2. Thresholds on the segment's median. Segments' medians above the first element are considered as gains and below the second value as losses.
向量的长度为2。阈值段的中位数。分部“中位数以上的第一个元素被视为收益及以下作为第二个值亏损。
参数：minSeg
Minimum length of segments. Default = 3.
段的最小长度。默认值为3。
参数：eps
Real value greater or equal zero. A breakpoint is only possible between to consecutive values of x that have a distance of at least "eps". Default = 0.
真正的价值大于或等于零。断点是唯一可能的“EPS”至少有一个距离x的连续值之间。默认值= 0。
参数：delta
Positive integer. A parameter to make the segmentation more efficient. If the statistics of a breakpoint lowers while extending the window, the algorithm extends the windows by "delta" more points until it stops. Default = 20.
正整数。一个参数，以使分割更有效。如果一个断点的统计数字降低，同时延长窗口，算法的扩展，多点“Delta”的窗口，直到它停止。默认值= 20。
参数：maxInt
The maximum length of a segment left of the breakpoint and right of the breakpoint that is considered. Default = 40.
断点断点被认为有权留下了段的最大长度。默认值= 40。
参数：squashing
An experimental parameter that squashes the values "x" before segmentation. Should be left to zero, which means that squashing is not performed. Default = 0.
南瓜实验参数值“X”之前分割。应留给为零，这意味着不进行压片。默认值= 0。
参数：cyberWeight
The "nu" parameter of the cyber t-test. Default = 50.
“女”的网络T-测试参数。默认值= 50。
参数：segPlot
Logical indicating whether the result of the segmentation a algorithm should be plotted. Default = TRUE.
逻辑指示是否应绘制算法的分割结果。默认= TRUE。
参数：...
additional parameters passed to the plotting function.
额外的参数传递给绘图功能。
值----------Value----------
A data frame containing the segments.
一个数据框包含段。
