在ggplot2中显示频率和barplot [英] Show frequencies along with barplot in ggplot2
问题描述
我试图在barplot内显示频率...呃,我想要它们在某处图表中:在酒吧下方,酒吧内,酒吧上方或图例区域中。我记得(我可能是错的),它可以在 ggplot2
中完成。这可能很简单...至少看起来很简单。代码如下:
pre $ $ $ $ $ $ $ pre $ p $ ()
有没有可能让频率嵌入图表中?
geom_text
是
p + geom_bar()+ stat_bin(aes(label = .. count ..),vjust = 0,
geom =text,position =identity)
要调整标签的y位置,您可以在 stat_bin
中使用 y =
审美性:例如, y = .. count .. + 1
会将标签放在一个单位上方。
上面还有如果您在内部使用 geom_text
和 stat =bin
,则可以使用。
I'm trying to display frequencies within barplot ... well, I want them somewhere in the graph: under the bars, within bars, above bars or in the legend area. And I recall (I may be wrong) that it can be done in ggplot2
. This is probably an easy one... at least it seems easy. Here's the code:
p <- ggplot(mtcars)
p + aes(factor(cyl)) + geom_bar()
Is there any chance that I can get frequencies embedded in the graph?
geom_text
is tha analog of text
from base graphics:
p + geom_bar() + stat_bin(aes(label=..count..), vjust=0,
geom="text", position="identity")
If you want to adjust the y-position of the labels, you can use the y=
aesthetic within stat_bin
: for example, y=..count..+1
will put the label one unit above the bar.
The above also works if you use geom_text
and stat="bin"
inside.
