描述----------Description----------
Spatial locations of cases of childhood leukaemia and lymphoma, and randomly-selected controls, in North Humberside. A marked point pattern.
儿童白血病和淋巴瘤，并随机选择的控制，在北亨伯赛德的情况下的空间位置。一个显着的点模式。
用法----------Usage----------
data(humberside)
格式----------Format----------
The dataset humberside is an object of class "ppp" representing a marked point pattern. Entries include
的数据集humberside是一个对象的类"ppp"的较明显的点模式。参赛作品包括：
Cartesian x-coordinate of home address
笛卡尔x坐标的家庭地址
Cartesian y-coordinate of home address
笛卡尔y坐标的家庭地址
factor with levels case and control
因素与水平case和control
indicating whether this is a disease case
指出这是否是一种疾病的情况下，
See ppp.object for details of the format.
见ppp.object的格式的详细信息。
The dataset humberside.convex is an object of the same format, representing the same point pattern data, but contained in a larger, 5-sided convex polygon.
的数据集humberside.convex一个目的是相同的格式，代表相同的点图案数据的，但包含在一个更大，5面的凸多边形。
笔记----------Notes----------
Cuzick and Edwards (1990) first presented and analysed these data.
Cuzick非参数和Edwards（1990）首次提出和分析这些数据。
The data record 62 cases of childhood leukaemia and lymphoma diagnosed in the North Humberside region of England between 1974 and 1986, together with 141 controls selected at random from the birth register for the same period.
数据记录的62例儿童白血病和淋巴瘤的诊断在英国亨伯赛德郡区域在1974年和1986年之间，选择随机从诞生的注册同期141控制。
The data are represented as a marked point pattern, with the points giving the spatial location of each individual's home address (actually, the centroid for the postal code) and the marks identifying cases and controls.
数据被表示为显着的点图案，与给每个个人的家乡地址的空间位置（实际上，邮政代码）的质心和识别病例组和对照组的标记点。
Coordinates are expressed in units of 100 metres, and the resolution is 100 metres. At this resolution, there are some duplicated points.
坐标表示单位为100米，分辨率为100米。在这项决议中，有一些重复的点。
Two versions of the dataset are supplied, both containing the same point coordinates, but using different windows. The dataset humberside has a polygonal window with 102 edges which closely approximates the Humberside region, while humberside.convex has a convex 5-sided polygonal window originally used by Diggle and Chetwynd (1991) and shown in Figure 1 of that paper. (This pentagon has been modified slightly from the original data, by shifting two vertices horizontally by 1 unit, so that the pentagon contains all the data points.)
提供两个版本的数据集，它们都包含相同的点的坐标，但使用不同的Windows。的数据集的humberside具有多边形窗口102边缘接近享伯赛德区域的，而humberside.convex具有凸5面的多边形窗口Diggle和Chetwynd的（1991）和最初所使用的图1中所示该文件。 （此五角大楼已稍作修改，从原来的数据，的两个顶点水平移1个单位，所以说，五角大楼包含的所有数据点）。
