描述----------Description----------
These are methods for objects of class "histogram", typically produced by hist.
这些都是生产，通常由"histogram"类hist对象的方法。
用法----------Usage----------
## S3 method for class 'histogram'
plot(x, freq = equidist, density = NULL, angle = 45,
col = NULL, border = par("fg"), lty = NULL,
main = paste("Histogram of",
paste(x$xname, collapse="\n")),
sub = NULL, xlab = x$xname, ylab,
xlim = range(x$breaks), ylim = NULL,
axes = TRUE, labels = FALSE, add = FALSE,
ann = TRUE, ...)
## S3 method for class 'histogram'
lines(x, ...)
参数----------Arguments----------
参数：x
a histogram object, or a list with components density, mid, etc, see hist for information about the components of x.
histogram对象，或与组件列表density，mid等，请参阅hist为x组件信息。
参数：freq
logical; if TRUE, the histogram graphic is to present a representation of frequencies, i.e, x$counts; if FALSE, relative frequencies (probabilities), i.e., x$density, are plotted. The default is true for equidistant breaks and false otherwise.
逻辑;如果TRUE，直方图图形是呈现代表性的频率，即x$counts;如果FALSE，相对频率（概率），即x$density，绘制。默认值是true为等距离breaks“，否则为false。
参数：col
a colour to be used to fill the bars. The default of NULL yields unfilled bars.
要使用一种颜色，填补了条形。 NULL默认产生悬空的条形。
参数：border
the color of the border around the bars.
颜色的边界附近的条形。
参数：angle, density
select shading of bars by lines: see rect.
选择线棒的阴影：看到rect。
参数：lty
the line type used for the bars, see also lines.
用于条形的线路类型，也看到lines。
参数：main, sub, xlab, ylab
these arguments to title have useful defaults here.
这些title的参数这里有有用的默认。
参数：xlim, ylim
the range of x and y values with sensible defaults.
合理的默认值x和y值的范围。
参数：axes
logical, indicating if axes should be drawn.
逻辑，说明是否应制定轴。
参数：labels
logical or character. Additionally draw labels on top of bars, if not FALSE; if TRUE, draw the counts or rounded densities; if labels is a character, draw itself.
逻辑或字符。此外，借鉴条形顶部的标签，如果没有FALSE如果TRUE，提请计数或圆形密度; labels如果是character，自行绘制。
参数：add
logical. If TRUE, only the bars are added to the current plot. This is what lines.histogram(*) does.
逻辑。如果TRUE，唯一的条形都添加到当前的图。这是什么lines.histogram(*)不。
参数：ann
logical. Should annotations (titles and axis titles) be plotted?
逻辑。应说明（标题和轴标题）绘制？
参数：...
further graphical parameters to title and axis.
进一步的图形参数title和axis。
Details
详情----------Details----------
lines.histogram(*) is the same as plot.histogram(*, add = TRUE).
lines.histogram(*)是plot.histogram(*, add = TRUE)相同。
参见----------See Also----------
hist, stem, density.
hist，stem，density。
举例----------Examples----------
(wwt <- hist(women$weight, nclass = 7, plot = FALSE))
plot(wwt, labels = TRUE) # default main & xlab using wwt$xname[默认的主XLab中使用WWT $ XName的]
plot(wwt, border = "dark blue", col = "light blue",
main = "Histogram of 15 women's weights", xlab = "weight [pounds]")
## Fake "lines" example, using non-default labels:[＃假“线”，例如，使用非默认的标签：]
w2 <- wwt; w2$counts <- w2$counts - 1
lines(w2, col = "Midnight Blue", labels = ifelse(w2$counts, "> 1", "1"))
