描述----------Description----------
Spatial locations of cases of cancer of the larynx and cancer of the lung, and the location of a disused industrial incinerator. A marked point pattern.
癌症的肺，喉和癌症的一个废弃的工业焚烧炉的位置的情况下的空间位置。一个显着的点模式。
用法----------Usage----------
data(chorley)
格式----------Format----------
The dataset chorley is an object of class "ppp" representing a marked point pattern. Entries include
的数据集chorley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 larynx and lung
因素与水平larynx和lung
indicating whether this is a case of cancer of the larynx
这是否是喉癌的情况下，
See ppp.object for details of the format.
见ppp.object的格式的详细信息。
The dataset chorley.extra is a list with two components. The first component plotit is a function which will plot the data in a sensible fashion. The second component incin is a list with entries x and y giving the location of the industrial incinerator.
的数据集chorley.extra是一个两部分组成。第一部分plotit是一个函数，它会在一个合理的方式绘制数据。第二成分incin是一个与条目列表x和y给工业焚烧炉的位置。
Coordinates are given in kilometres, and the resolution is 100 metres (0.1 km)
坐标中给出公里，分辨率为100米（0.1公里）
笔记----------Notes----------
The data give the precise domicile addresses of new cases of cancer of the larynx (58 cases) and cancer of the lung (978 cases), recorded in the Chorley and South Ribble Health Authority of Lancashire (England) between 1974 and 1983. The supplementary data give the location of a disused industrial incinerator.
的数据提供精确的住所地址喉癌的新发病例（58例）和肺癌（978例），记录在乔利和的南Ribble卫生局在1974年和1983年的兰开夏郡（英格兰）的癌症。补充数据的位置让给一个废弃的工业焚烧炉。
The data were first presented and analysed by Diggle (1990). They have subsequently been analysed by Diggle and Rowlingson (1994) and Baddeley et al. (2005).
数据首先被提出和分析者Diggle（1990）。随后，他们Diggle和Rowlingson（1994年）和巴德利等进行了分析。 （2005年）。
The aim is to assess evidence for an increase in the incidence of cancer of the larynx in the vicinity of the now-disused industrial incinerator. The lung cancer cases serve as a surrogate for the spatially-varying density of the susceptible population.
其目的是评估证据，现在废弃的工业焚烧炉附近的喉癌症的发病率增加。肺癌的情况下，作为一个替代的空间密度不同的易感人群。
The data are represented as a marked point pattern, with the points giving the spatial location of each individual's home address and the marks identifying whether each point is a case of laryngeal cancer or lung cancer.
数据被表示为显着的点图案，与给每个个人的家乡地址和识别每个点是否是一个箱子喉癌或肺癌的标记的空间位置的点。
Coordinates are in kilometres, and the resolution is 100 metres (0.1 km).
坐标的单位是公里，分辨率为100米（0.1公里）。
The dataset chorley has a polygonal window with 132 edges which closely approximates the boundary of the Chorley and South Ribble Health Authority.
的数据集chorley有一个多边形窗口有132个边缘非常接近乔利和边界的南Ribble卫生监督所。

Coordinates of cases were provided by the Chorley and South Ribble Health Authority, and were kindly supplied by Professor Peter Diggle. Region boundary was digitised by Adrian Baddeley, 2005, from a photograph of an Ordnance Survey map.
坐标的情况下，提供的乔利与南Ribble卫生监督所，，教授彼得Diggle提供的。区边界数字化阿德里安 - 巴德利，2005年，全国地形测量局图的照片。
