1-D Scatter Plots
一维散点图
译者：生物统计家园网 机器人LoveR
描述----------Description----------
stripchart produces one dimensional scatter plots (or dot plots) of the given data. These plots are a good alternative to boxplots when sample sizes are small.
stripchart给定的数据产生一个三维散射图（点图）。这些图，boxplot的是一个很好的选择，当样本量小。
用法----------Usage----------
stripchart(x, ...)
## S3 method for class 'formula'[类formula的方法]
stripchart(x, data = NULL, dlab = NULL, ...,
subset, na.action = NULL)
## Default S3 method:[默认方法]
stripchart(x, method = "overplot", jitter = 0.1, offset = 1/3,
vertical = FALSE, group.names, add = FALSE,
at = NULL, xlim = NULL, ylim = NULL,
ylab=NULL, xlab=NULL, dlab="", glab="",
log = "", pch = 0, col = par("fg"), cex = par("cex"),
axes = TRUE, frame.plot = axes, ...)
参数----------Arguments----------
参数：x
the data from which the plots are to be produced. In the default method the data can be specified as a single numeric vector, or as list of numeric vectors, each corresponding to a component plot. In the formula method, a symbolic specification of the form y ~ g can be given, indicating the observations in the vector y are to be grouped according to the levels of the factor g. NAs are allowed in the data.
数据从该图是待产。在默认的方法，可以将数据作为一个单一的数字向量，指定或数字向量的列表，每个对应一个组件剧情。象征性规范的形式formula在y ~ g方法，可以给出说明矢量y要按照水平的因素g的意见。 NAS在数据允许。
参数：data
a data.frame (or list) from which the variables in x should be taken.
数据框（或列表）变量x应采取的。
参数：subset
an optional vector specifying a subset of observations to be used for plotting.
指定一个可选的向量绘图观测的子集。
参数：na.action
a function which indicates what should happen when the data contain NAs. The default is to ignore missing values in either the response or the group.
一个函数，它表示数据时，包含NA的，应该发生什么。默认是忽略缺失值，无论是在响应或组。
参数：...
additional parameters passed to the default method, or by it to plot, points, axis and title to control the appearance of the plot.
额外的参数传递给默认的方法，或plot，points，axis和title控制图的外观。
参数：method
the method to be used to separate coincident points. The default method "overplot" causes such points to be overplotted, but it is also possible to specify "jitter" to jitter the points, or "stack" have coincident points stacked. The last method only makes sense for very granular data.
该方法可用于分离重合点。默认的方法"overplot"导致等点overplotted的，但它也可以指定"jitter"抖动点，或"stack"重合点堆积。最后的方法，只对非常细微的数据的意义。
参数：jitter
when method="jitter" is used, jitter gives the amount of jittering applied.
当method="jitter"，jitter给出了应用的抖动量。
参数：offset
when stacking is used, points are stacked this many line-heights (symbol widths) apart.
堆叠使用时，点堆积很多线高度（象征宽度）除了。
参数：vertical
when vertical is TRUE the plots are drawn vertically rather than the default horizontal.
垂直时TRUE图绘制，而不是默认的水平，垂直。
参数：group.names
group labels which will be printed alongside (or underneath) each plot.
组，将每个小区旁边（或下方）印标签。
参数：add
logical, if true add the chart to the current plot.
逻辑，如果属实，目前积添加图表。
参数：at
numeric vector giving the locations where the charts should be drawn, particularly when add = TRUE; defaults to 1:n where n is the number of boxes.
数字向量应绘制图表的位置，尤其是当add = TRUE;默认1:n其中n是箱数。
参数：ylab, xlab
labels: see title.
标签：看到title。
参数：dlab, glab
alternate way to specify axis labels: see "Details".
另一种方法来指定轴标签：见“详细资料”。
参数：xlim, ylim
plot limits: see plot.window.
图限制：见plot.window。
参数：log
on which axes to use a log scale: see plot.default
上轴使用一个日志规模：见plot.default
参数：pch, col, cex
Graphical parameters: see par.
图形参数：看到par。
参数：axes, frame.plot
Axis control: see plot.default
轴控制：看到plot.default
Details
详情----------Details----------
Extensive examples of the use of this kind of plot can be found in Box, Hunter and Hunter or Seber and Wild.
可以在广泛使用这种图的例子中找到的，猎人和猎人或Seber和野生。
The dlab and glab labels may be used instead of xlab and ylab if those are not specified. dlab applies to the continuous data axis (the X axis unless vertical is TRUE), glab to the group axis.
dlab和glab标签可以用来代替xlab和ylab如果这些都没有指定。 dlab适用于连续数据轴（X轴除非vertical是TRUE）glab组轴。
举例----------Examples----------
x <- stats::rnorm(50)
xr <- round(x, 1)
stripchart(x) ; m <- mean(par("usr")[1:2])
text(m, 1.04, "stripchart(x, \"overplot\")")
stripchart(xr, method = "stack", add = TRUE, at = 1.2)
text(m, 1.35, "stripchart(round(x,1), \"stack\")")
stripchart(xr, method = "jitter", add = TRUE, at = 0.7)
text(m, 0.85, "stripchart(round(x,1), \"jitter\")")
stripchart(decrease ~ treatment,
main = "stripchart(OrchardSprays)",
vertical = TRUE, log = "y", data = OrchardSprays)
stripchart(decrease ~ treatment, at = c(1:8)^2,
main = "stripchart(OrchardSprays)",
vertical = TRUE, log = "y", data = OrchardSprays)
