译者：生物统计家园网 机器人LoveR
描述----------Description----------
This function allows the user to place smoothScatter plots in lattice graphics.
此功能允许用户将smoothScatter点阵图形的图。
用法----------Usage----------
panel.smoothScatter(x, y = NULL,
nbin = 64, cuts = 255,
bandwidth,
colramp,
nrpoints = 100,
transformation = function(x) x^0.25,
pch = ".",
cex = 1, col="black",
range.x,
...,
raster = FALSE,
subscripts,
identifier = "smoothScatter")
参数----------Arguments----------
参数：x
Numeric vector containing x-values or n by 2 matrix containing x and y values.
2矩阵X和Y值的x值或n的数字向量。
参数：y
Numeric vector containing y-values (optional). The length of x must be the same as that of y.
数字向量的y值（可选）。 x长度必须是作为y相同。
参数：nbin
Numeric vector of length 1 (for both directions) or 2 (for x and y separately) containing the number of equally spaced grid points for the density estimation.
数值向量的长度为1（两个方向）或2（分别为X和Y），其中包含等距格点的密度估计的数目。
参数：cuts
number of cuts defining the color gradient
定义颜色渐变的削减
参数：bandwidth
Numeric vector: the smoothing bandwidth. If missing, these functions come up with a more or less useful guess. This parameter then gets passed on to the function bkde2D.
数字向量：平滑的带宽。如果缺少这些功能拿出一个或多或少有用的猜测。此参数被传递给函数bkde2D。
参数：colramp
Function accepting an integer n as an argument and returning n colors.
函数接受一个整数n作为参数和返回n颜色。
参数：nrpoints
Numeric vector of length 1 giving number of points to be superimposed on the density image. The first nrpoints points from those areas of lowest regional densities will be plotted. Adding points to the plot allows for the identification of outliers. If all points are to be plotted, choose nrpoints = Inf.
长度为1的数字矢量点的数量，密度图像上叠加。第一nrpoints点从这些区域的最低区域密度将绘制。加分的图，允许为离群鉴定。如果所有的点都被绘制，选择nrpoints = Inf。
参数：transformation
Function that maps the density scale to the color scale.
函数映射密度规模的色阶。
参数：pch, cex
graphical parameters for the nrpoints “outlying” points shown in the display
nrpoints“外围”点在显示器上显示的图形参数
参数：range.x
see bkde2D for details.
看到bkde2D详情。
参数：col
points color parameter
points颜色参数
参数：...
Further arguments that are passed on to panel.levelplot.
进一步传递panel.levelplot的论据。
参数：raster
logical; if TRUE, panel.levelplot.raster is used, making potentially smaller output files.
逻辑;如果TRUE，panel.levelplot.raster使用，使潜在的更小的输出文件。
参数：subscripts
ignored, but necessary for handling of ... in certain situations. Likely to be removed in future.
被忽略，但必要的处理，...在某些情况下。在未来可能会删除。
参数：identifier
A character string that is prepended to the names of grobs that are created by this panel function.
一个字符串，前面的名称，由本面板功能创建的grobs。
Details
详情----------Details----------
This replicates the display part of the smoothScatter function by replacing standard graphics calls by grid-compatible ones.
复制取代电网兼容的标准图形来电显示smoothScatter函数的一部分。
值----------Value----------
The function is called for its side effects, namely the production of the appropriate plots on a graphics device.
它的副作用，即合适的图上的图形设备的生产函数被调用。

举例----------Examples----------
ddf <- as.data.frame(matrix(rnorm(40000), ncol = 4) + 3 * rnorm(10000))
ddf[, c(2,4)] <- (-ddf[, c(2,4)])
xyplot(V1 ~ V2 + V3, ddf, outer = TRUE,
panel = panel.smoothScatter, aspect = "iso")
splom(ddf, panel = panel.smoothScatter, nbin = 64, raster = TRUE)
