Logical flag indicating whether the new code in rmh.default which makes the results scalable (invariant to change of units) should be used. In order to recover former behaviour (so that previous results can be reproduced) set this option equal to FALSE. See the “Warning” section in the help for rmh() for more detail.
逻辑指示标志的新代码是否rmh.default这使得可扩展的结果（单位不变的改变），应使用。为了恢复以前的行为（以前的结果可以被复制）设置此等于FALSE的选项。在为rmh()更详细的帮助，请参阅“警告”一节。

Logical flag indicating whether the functions owin and as.owin should check the validity of polygon data. It is advisable to leave this set to TRUE. If you set checkpolygons=FALSE, no checking will be performed, making it possible to create window objects whose topology is garbled. This can be useful for inspecting spatial data that contain errors, for example, when converting data from shapefiles. However, other functions in spatstat may return incorrect answers on these data.
逻辑标志指示的功能是否owin和as.owin应该检查多边形数据的有效性。这是最好离开这个设置为TRUE。如果你设置checkpolygons=FALSE，将不检查，它可以创建窗口对象的拓扑结构是乱码。用于检查空间包含错误的数据，例如，从shapefile转换数据时，这可能是有用的。然而，其他的功能在spatstat这些数据可能会返回不正确的答案。
Logical flag indicating whether the functions psp and as.psp should check the validity of line segment data (in particular, checking that the endpoints of the line segments are inside the specified window). It is advisable to leave this flag set to TRUE.
逻辑标志，指示是否功能psp和as.psp应检查的有效性线段数据（特别是检查指定的窗口内的端点的线段）。这是最好，离开这个标志设置为TRUE。
Logical flag indicating whether the polygon clipping library gpclib can be used. The default is FALSE, which means that the package gpclib is not loaded, and certain polygon operations (such as the intersection and union of polygons) will be approximated by raster operations. If this option is re-set to TRUE, then the package gpclib will be loaded, and polygon operations such as the union and intersection of polygons will result in a polygon. The licence for gpclib is not Free Open Source and explicitly forbids commercial use. See library(help=gpclib). If you are using spatstat for commercial purposes, this option should remain set to FALSE.
逻辑标志指示是否多边形裁剪库gpclib可以使用。默认是FALSE，这意味着套件“gpclib没有加载，和某些多边形的操作（如交集和并集多边形）将近似光栅操作。如果此选项设置为TRUE，然后包gpclib会被加载，和多边形的操作，如多边形的并集和交集，将导致一个多边形。 gpclib的许可证是免费开源，并明确禁止商业用途。见library(help=gpclib)。如果您使用的是spatstat用于商业用途，此选项应保持设置为FALSE。
The maximum permitted size (rows times columns) of matrices generated by spatstat's internal code. Used by ppm and predict.ppm (for example) to decide when to split a large calculation into blocks. Defaults to 2^24=16777216.
允许的最大大小（行次列）矩阵所产生的spatstat的内部代码。用于通过ppm和predict.ppm（例如），以决定何时把一个大的计算成块。默认为2^24=16777216的。
The maximum value of n for which runif(n) will not generate an error (possible errors include failure to allocate sufficient memory, and integer overflow of n). An attempt to generate more than this number of random points triggers a warning from runifpoint and other functions. Defaults to 1e6.
的最大值n的runif(n)不会产生一个错误（可能的错误包括未能分配足够的内存，和整数溢出n）。尝试超过这个数量的随机点产生更多的触发警告runifpoint等功能。默认为1e6的。

Default rule used by print.ppm to decide whether to calculate and print standard errors of the estimated coefficients of the model. One of the strings "always", "never" or "poisson" (the latter indicating that standard errors will be calculated only for Poisson models). The default is "poisson" because the calculation for non-Poisson models can take a long time.
默认规则使用print.ppm，以决定是否计算和打印模型的估计系数的标准误差。的字符串"always"，"never"或"poisson"泊松模型将只计算标准误差（后者）。默认值是"poisson"因为非泊松模型的计算可能需要很长的时间。
