ggplot中的特殊变量文档(..count ..,..density ..等) [英] Documentation for special variables in ggplot (..count.., ..density.., etc.)
问题描述
ggplot2中的stats_函数创建特殊变量,例如 stat_bin2d
创建一个名为 .. count ..
的特殊变量。我在哪里可以找到文档列出哪些stat_函数返回哪些特殊变量?
我已经看过主要的ggplot2 文档页面和R在线帮助。我尝试阅读stat_bin2d的源代码,但它使用了我不懂的语言 - 我不知道如何获得 StatBin2d $ new(...)
。
大部分内容都记录在帮助页面的值部分,例如<$
$ b
值:
?stat_boxplot 带有附加列的数据框:
width: boxplot的宽度
ymin:lower whisker =最小观察值大于或等于
lower hinge - 1.5 * IQR
下:下铰链,25%分位数
notchlower:缺口下边缘=中位数-1.58 * IQR / sqrt(n)
中间值:中值,50%分位数
notchupper:缺口上缘=中值+ 1.58 * IQR / sqrt(n)
上部:上部铰链,75%分位数
ymax:上胡须=最大观察小于或等于
上铰链+ 1.5 * IQR
我建议为那些没有记录的人提交错误报告。对于 stat_bin2d
错误报告 >,但它是固定封闭的。如果你创建了一个新的错误报告,你可以参考那个。
The stats_ functions in ggplot2 create special variables, e.g. stat_bin2d
creates a special variable called ..count..
. Where can I find documentation listing which special variables are returned by which stat_ function?
I've looked on the main ggplot2 documentation pages, and in R online help. I tried reading the source code for stat_bin2d, but it uses bits of the language I don't understand -- I don't know how to get at the code behind StatBin2d$new(...)
.
Most of them are documented in the value section of the help pages, e.g., ?stat_boxplot
says
Value:
A data frame with additional columns:
width: width of boxplot
ymin: lower whisker = smallest observation greater than or equal to lower hinge - 1.5 * IQR
lower: lower hinge, 25% quantile
notchlower: lower edge of notch = median - 1.58 * IQR / sqrt(n)
middle: median, 50% quantile
notchupper: upper edge of notch = median + 1.58 * IQR / sqrt(n)
upper: upper hinge, 75% quantile
ymax: upper whisker = largest observation less than or equal to upper hinge + 1.5 * IQR
I suggest submitting bug reports for those that remain undocumented. There is a bug report for stat_bin2d
, but it was closed as fixed. If you create a new bug report you can refer to that one.
