Details
详细信息----------Details----------
Euler diagrams are drawn for mutually exclusive sets (cross.area == 0), inclusive sets (area1 == 0 or area2 == 0), and coincidental sets (area1 == 0 and area2 == 0) if euler.d == TRUE. The function defaults to placing the larger set on the left. The function also defaults to giving the first element of each argument to the larger set. inverted or rotation.degree can be used to reverse this.
欧拉图的绘制相互排斥的集合（cross.area == 0），包括套（area1 == 0或area2 == 0）和的巧合台（area1 == 0和area2 == 0)如果<所述>。功能默认将设置在左侧的功能也默认为每个参数的第一个元素的大量“euler.d == TRUE或inverted可以用来扭转这种。
值----------Value----------
Returns an object of class gList containing the grid objects that make up the diagram. Also displays the diagram in a graphical device unless specified with ind = FALSE. Grid::grid.draw can be used to draw the gList object in a graphical device.
返回一个对象，包含网格对象，使图中的类glist了。图中还显示一个图形化的设备，除非指定的IND = FALSE。可用于网格:: grid.draw，在图形设备到得出的glist的对象。
