Create a transition-definition matrix
创建一个过渡定义矩阵

描述----------Description----------
This function automatically creates a transition-definition matrix from a state sequence object to transform the state sequences into time stamped event sequences (in TSE format).
此功能会自动创建一个状态序列对象的状态序列，时间标记的事件序列（TSE格式）转换的过渡定义矩阵。
用法----------Usage----------
seqetm(seq, method = "transition", use.labels = TRUE,
sep = ">", bp = "", ep = "end")
参数----------Arguments----------
参数：seq
State sequence object from which transition events will be determined
状态转换事件的序列对象将确定
参数：method
The method to use. One of "transition", "period" or "state".
使用的方法。 "transition"，"period"或"state"之一。
参数：use.labels
If TRUE, transition names are built from state labels rather than from the alphabet.
如果TRUE，转变名是内置的，而不是从字母表的状态标签。
参数：sep
Separator to be used between the from-state and to-state that define the transition ("transition" method).
隔板之间要使用从状态和状态定义的过渡（“过渡”的方法）。
参数：bp
Prefix for beginning of period event names ("period" method)
前缀周期事件的名称开始的（"period"方法）
参数：ep
Prefix for end of period event names ("period" method)
结束周期事件的名称的前缀（"period"方法）
Details
详细信息----------Details----------
Warning!!!: State labels should not contain commas "," which are reserved for separating multiple events of a same transition!
警告！：国家标签不应该包含逗号","：“这是预留用于分隔多个事件的过渡！
One of three methods can be selected with the method argument:
method参数，可以选择以下三种方法之一：
"transition" generates a single (from-state > to-state) event for each found transition and a distinct start-state event for each different sequence start;
"transition"生成一个单一的（从状态>状态）事件，每一个找到的过渡和不同的起始状态为每个不同的顺序启动的事件;
"period" generates a pair of events (end-state-event, start-state-event) for each found transition, a start-state event for the beginning of the sequence and an end-state event for the end of the sequence; names used for end-state and start-state names can be controlled with the bp and ep arguments;
"period"产生一个对事件（最终状态的情况下，开始状态事件）为每一个找到的转变，一开始状态事件的序列开始和结束的最终状态事件序列，为最终状态和启动状态名称中使用的名称是可以控制的bp和ep参数;
"state" generates only the to-state event of each found transition (useful for analysing state sequences with methods for event sequences);
"state"只产生对国家的每一个找到的过渡事件的（有用的，状态序列分析事件序列的方法）;
值----------Value----------
The transition-definition matrix.
过渡定义矩阵。

实例----------Examples----------
## Creating a state sequence object from columns 13 to 24[＃创建一个状态序列对象，从13日至24列]
## in the 'actcal' example data set[＃在“actcal”示例数据集]
data(actcal)
actcal.seq <- seqdef(actcal,13:24,
labels=c("FullTime", "PartTime", "LowPartTime", "NoWork"))
## Creating a transition matrix, one event per transition[＃创建一个转换矩阵，每一个事件过渡]
seqetm(actcal.seq,method = "transition")
## Creating a transition matrix, single to-state events[＃创建一个转换矩阵，单一的状态事件]
seqetm(actcal.seq,method = "state")
## Creating a transition matrix, two events per transition[＃创建一个转换矩阵，每两个事件过渡]
seqetm(actcal.seq,method = "period")
## changing the prefix of period start event.[＃改变周期启动事件的前缀。]
seqetm(actcal.seq,method = "period", bp="begin")
