描述----------Description----------
Applies a vector shift to a window
应用向量转移到一个窗口
用法----------Usage----------
## S3 method for class 'owin'
shift(X, vec=c(0,0), ..., origin=NULL)
参数----------Arguments----------
参数:X
Window (object of class "owin").
窗口(类的对象"owin")。
参数:vec
Vector of length 2 representing a translation.
矢量长度为2翻译。
参数:...
Ignored
忽视
参数:origin
Character string determining a location that will be shifted to the origin. Options are "centroid", "midpoint" and "bottomleft". Partially matched.
字符串判定的位置,将被转移到原点。选项"centroid","midpoint"和"bottomleft"。部分匹配。
Details
详细信息----------Details----------
The window is translated by the vector vec. This is a method for the generic function shift.
该窗口被翻译由矢量vec。这是一个方法的通用函数shift。
If origin is given, then it should be one of the character strings "centroid", "midpoint" or "bottomleft". The argument vec will be ignored; instead the shift will be performed so that the specified geometric location is shifted to the origin. If origin="centroid" then the centroid of the window will be shifted to the origin. If origin="midpoint" then the centre of the bounding rectangle of the window will be shifted to the origin. If origin="bottomleft" then the bottom left corner of the bounding rectangle of the window will be shifted to the origin.
origin如果是给定的,那么它应该是一个字符串的"centroid","midpoint"或"bottomleft"。 vec的参数将被忽略,而不是将执行移位,转移到指定的几何位置的起源。如果origin="centroid"然后在窗口的质心将被转移到原点的。如果origin="midpoint"窗口的边界矩形的中心将转移到原点的。如果origin="bottomleft"然后在左下角的窗口的边框将被转移到原点的。
值----------Value----------
Another window (of class "owin") representing the result of applying the vector shift.
另一个窗口(类"owin")应用矢量移位的结果。

W <- owin(c(0,1),c(0,1))
X <- shift(W, c(2,3))
## Not run: [#不运行:]
plot(W)
# no discernible difference except coordinates are different[没有明显的差异是不同的,除了坐标]
## End(Not run)[#(不执行)]
shift(W, origin="mid")
