描述----------Description----------
This function produces two variants of the conditioning plots discussed in the reference below.
此功能参考下面讨论的空调图产生两个变种。
用法----------Usage----------
coplot(formula, data, given.values, panel = points, rows, columns,
show.given = TRUE, col = par("fg"), pch = par("pch"),
bar.bg = c(num = gray(0.8), fac = gray(0.95)),
xlab = c(x.name, paste("Given :", a.name)),
ylab = c(y.name, paste("Given :", b.name)),
subscripts = FALSE,
axlabels = function(f) abbreviate(levels(f)),
number = 6, overlap = 0.5, xlim, ylim, ...)
co.intervals(x, number = 6, overlap = 0.5)
参数----------Arguments----------
参数：formula
a formula describing the form of conditioning plot. A formula of the form y ~ x | a indicates that plots of y versus x should be produced conditional on the variable a. A formula of the form y ~ x| a * b indicates that plots of y versus x should be produced conditional on the two variables a and b. All three or four variables may be either numeric or factors. When x or y are factors, the result is almost as if as.numeric() was applied, whereas for factor a or b, the conditioning (and its graphics if show.given is true) are adapted.
公式空调图的形式。公式的形式y ~ x | a表明图y与x应生产条件变量a。公式的形式y ~ x| a * b表明图y与x须出示的两个变量a和b条件。所有三个或四个变量可以是数字或因素。当x或y的因素，结果几乎是一样如果as.numeric()应用，而为的因素a或b，空调（和它的图形适应show.given如果是真的）。
参数：data
a data frame containing values for any variables in the formula. By default the environment where coplot was called from is used.
一个数据框包含公式中的任何变量的值。默认情况下，其中coplot被称为环境。
参数：given.values
a value or list of two values which determine how the conditioning on a and b is to take place. When there is no b (i.e., conditioning only on a), usually this is a matrix with two columns each row of which gives an interval, to be conditioned on, but is can also be a single vector of numbers or a set of factor levels (if the variable being conditioned on is a factor). In this case (no b), the result of co.intervals can be used directly as given.values argument.
一个值或两个值确定名单a和b是要发生的空调。当有没有b，通常这是一个两列矩阵的每一行给出了一个区间，条件，但也可以是一个单一的（即，只对a空调）向量的数字或一组因子水平（如果条件变量是一个因素）。在这种情况下（没有b），co.intervalsgiven.values参数可用作直接的结果。
参数：panel
a function(x, y, col, pch, ...) which gives the action to be carried out in each panel of the display. The default is points.
function(x, y, col, pch, ...)这使在每个显示面板进行操作。默认points。
参数：rows
the panels of the plot are laid out in a rows by columns array. rows gives the number of rows in the array.
图板被放置在一个由rows阵列columns。 rows给数组中的行的数量。
参数：columns
the number of columns in the panel layout array.
在面板布局阵列的列数。
参数：show.given
logical (possibly of length 2 for 2 conditioning variables): should conditioning plots be shown for the corresponding conditioning variables (default TRUE).
逻辑（可能是2调节变量的长度2）：空调图应进行相应的调节变量显示（默认的TRUE）。
参数：col
a vector of colors to be used to plot the points. If too short, the values are recycled.
要使用的颜色向量绘制点。如果太短，回收价值。
参数：pch
a vector of plotting symbols or characters. If too short, the values are recycled.
矢量绘制符号或字符。如果太短，回收价值。
参数：bar.bg
a named vector with components "num" and "fac" giving the background colors for the (shingle) bars, for numeric and factor conditioning variables respectively.
一个组件的命名向量"num"和"fac"给（瓦）条形的背景颜色，分别为数字和因素调节变量。
参数：xlab
character; labels to use for the x axis and the first conditioning variable. If only one label is given, it is used for the x axis and the default label is used for the conditioning variable.
字符;标签使用的X轴和第一调节变量。如果只有一个标签，它是用于X轴和调节变量的默认标签。
参数：ylab
character; labels to use for the y axis and any second conditioning variable.
字符;标签使用的Y轴和任何第二个调节变量。
参数：subscripts
logical: if true the panel function is given an additional (third) argument subscripts giving the subscripts of the data passed to that panel.
逻辑：如果属实面板功能给出一个额外的（三）subscripts提供的数据传递给该面板标参数。
参数：axlabels
function for creating axis (tick) labels when x or y are factors.
函数用于创建轴（打勾）标签，当X或Y的因素。
参数：number
integer; the number of conditioning intervals, for a and b, possibly of length 2. It is only used if the corresponding conditioning variable is not a factor.
整数;空调的时间间隔的数量，可能长度为2，A和B。它仅用于相应的调节变量是不是一个factor。
参数：overlap
numeric < 1; the fraction of overlap of the conditioning variables, possibly of length 2 for x and y direction. When overlap < 0, there will be gaps between the data slices.
数字<1;可能的X和Y方向长度为2，调节变量的重叠部分。 <0时，重叠，会有资料片之间的差距。
参数：xlim
the range for the x axis.
为x轴的范围。
参数：ylim
the range for the y axis.
y轴的范围。
参数：...
additional arguments to the panel function.
面板功能的附加参数。
参数：x
a numeric vector.
数字向量。
Details
详情----------Details----------
In the case of a single conditioning variable a, when both rows and columns are unspecified, a "close to square" layout is chosen with columns >= rows.
在一个单一的调节变量a，当两个rows和columns是不确定的，“接近正方形的布局与columns >= rows选择。
In the case of multiple rows, the order of the panel plots is from the bottom and from the left (corresponding to increasing a, typically).
在多个rows，面板图的顺序是从底部，从左边（对应增加a，通常）。
A panel function should not attempt to start a new plot, but just plot within a given coordinate system: thus plot and boxplot are not panel functions.
一个面板功能不应该尝试启动一个新的图，但只是在给定的坐标系中的图：plot和boxplot是不是面板功能。
The rendering of arguments xlab and ylab is not controlled by par arguments cex.lab and font.lab even though they are plotted by mtext rather than title.
渲染参数xlab和ylab不控制par参数cex.lab和font.lab即使他们绘制mtext而不是 title。
值----------Value----------
co.intervals(., number, .) returns a (number x 2) matrix, say ci, where ci[k,] is the range of x values for the k-th interval.
co.intervals(., number, .)返回（numberx2）matrix的说cici[k,]是range<X >x次间隔值。

举例----------Examples----------
## Tonga Trench Earthquakes[＃汤加海沟地震]
coplot(lat ~ long | depth, data = quakes)
given.depth <- co.intervals(quakes$depth, number=4, overlap=.1)
coplot(lat ~ long | depth, data = quakes, given.v=given.depth, rows=1)
## Conditioning on 2 variables:[＃空调2个变量：]
ll.dm <- lat ~ long | depth * mag
coplot(ll.dm, data = quakes)
coplot(ll.dm, data = quakes, number=c(4,7), show.given=c(TRUE,FALSE))
coplot(ll.dm, data = quakes, number=c(3,7),
overlap=c(-.5,.1)) # negative overlap DROPS values[负重叠DROPS值]
## given two factors[＃给定的两个因素]
Index <- seq(length=nrow(warpbreaks)) # to get nicer default labels[获得更好的默认标签]
coplot(breaks ~ Index | wool * tension, data = warpbreaks,
show.given = 0:1)
coplot(breaks ~ Index | wool * tension, data = warpbreaks,
col = "red", bg = "pink", pch = 21,
bar.bg = c(fac = "light blue"))
## Example with empty panels:[＃空面板为例：]
with(data.frame(state.x77), {
coplot(Life.Exp ~ Income | Illiteracy * state.region, number = 3,
panel = function(x, y, ...) panel.smooth(x, y, span = .8, ...))
## y ~ factor -- not really sensible, but 'show off':[＃Y因子 - 不是真的很明智的，但“炫耀”：]
coplot(Life.Exp ~ state.region | Income * state.division,
panel = panel.smooth)
})
