描述----------Description----------
This function gives access to a sampling scenario which is based on the mapping radioactivity and the calculation of a radionuclide inventory within a water body. (A "firth" is a Scottish term for a long, narrow indentation of the sea coast at the mouth of a river.) Interest lies in nuclides which, on release into a water body, attach (absorb) to sediment in a manner which depends on the sediment particle size. Cobalt-60 and caesium-137 are examples of nuclides which exhibit this behaviour. In this sampling scenario, the map of sediment type is used to define regions of different particle size from which the sediment samples will be collected by grabs from a boat. The presence of strata therefore has to be considered, as the different types of material on the sea bed may affect the mean values of the measurements taken.
此函数给出访问这是基于映射放射性和计算内的水体的放射性核素的库存的采样方案。 （A河口是苏格兰语在河口海岸一个狭长的缩进。）的兴趣在于，释放到水体，将放射性核素（吸收）的方式沉积物这取决于泥沙颗粒的大小。钴60和铯-137的放射性核素表现出这种行为的例子。在本次抽样的情况下，沉积物类型的图是用来定义区域的不同的颗粒尺寸从该沉积物样品将收集从船的抓斗。因此，地层的存在已被认为是，因为在海床上的不同类型的材料，可能会影响所采取的测量的平均值。
The function displays a map and gives graphical control over a variety of sampling strategies. Once the user has drawn a sample, some simple predictions over the whole firth can be produced. The geoR package is used to construct these predictions.
该函数显示的图和图形的取样策略的各种控制。一旦用户已经绘制了样品，在整个河口湾一些简单的预测可以生产。 geoR包被用来构建这些预测。
用法----------Usage----------
rp.firth(hscale = NA, col.palette = rev(heat.colors(40)), col.se = "blue", file = NA,
parameters = NA, sleep = 0.5)
参数----------Arguments----------
参数：hscale
a scaling parameter which expands (>1) or contracts (<1) the size of the plot within the panel. This can be useful for projection onto a screen, for example. The vertical scale is set to the same value as the horizontal scale, to ensure that the plot is square. The default values are 1 on Unix platforms and 1.4 on Windows platforms.
缩放参数扩展（> 1）或合同（<1）的图在面板的大小。这可能是有用的投影到屏幕上，例如。垂直刻度设置为相同的值作为水平刻度，确保的图是正方形。在Unix平台上的默认值是1和1.4在Windows平台上。
参数：col.palette
the colour palette used to display the predicted and true spatial surfaces.
的彩色调色板，用于显示的预测值和真实空间的表面。
参数：col.se
the colour used to draw the standard error contours on the predicted surface.
使用的颜色绘制标准错误的预测表面的轮廓。
参数：file
the name of a file to which the sampled data will be written.
采样的数据将被写入的文件的名称。
参数：parameters
a list which can be used to change the parameters which control the simulated measurement data.
可用于改变控制模拟的测量数据的参数的列表。
参数：sleep
the duration in seconds of a pause while the necessary internal information is loaded into the panel. See Details.
的持续时间，以秒为单位的暂停而装入板的必要的内部信息。查看详细信息。

详细信息----------Details----------
The use of the function is discussed in the paper referenced below.
使用的功能在下面引用的纸张中讨论。
Once the data have been sampled, a data file may be saved for further analysis external to the rp.firth function, using the file argument. A convenient way of saving to the current working directory, for example to a file named firth.dmp, is to set the file argument to file.path(getwd(), "firth.dmp"). The load function can then be applied to the saved file to create an object called mururoa.data, which is a three-column matrix with the x and y locations in columns 1 and 2 and the observed values in column 3.
一旦数据被采样，数据文件可以保存为外部rp.firth功能的进一步分析，使用file参数。一种方便的方法的节省到当前的工作目录，例如，一个名为firth.dmp，是设置filefile.path(getwd(), "firth.dmp")参数。 load函数然后可以被施加到所保存的文件，创建一个对象叫做mururoa.data，这是一个三列的矩阵，列1和2中，x和y位置和列中所观察到的值3。
On some machines the R and Tcl/Tk code can become out of step because of the time taken to initialise panel with the large amount of internal information required for plotting. The sleep argument allows a pause for this to be completed before further rpanel instructions are executed. If the rpanel window displays with very small size, try increasing the value of sleep.
在某些机器上R和Tcl / Tk的代码可以成为走出一步，因为所花费的时间来初始化面板，所需的打印大量的内部信息。 sleep参数允许一个暂停前完成进一步rpanel指令的执行。如果rpanel窗口显示非常小的尺寸，尝试保值增值的sleep。
值----------Value----------
