错误：ggplot2中的stat_count（） [英] Error: stat_count() in ggplot2
问题描述
在我的许多程序中，我一直使用ggplot2来渲染图表。我已经将它们加载到shinyapps.io上，它们工作得很好。但是，当我尝试在我的机器上运行该程序时，出现以下错误：
错误：stat_count（）必须不能用于美学。
以下是示例代码：
ggplot（hashtg，aes（x = reorder（hashtag，Freq），y = Freq，fill = hashtag））+ geom_bar（stat =identity）+
geom_bar （aes（label = Freq），hjust = 1，color =white）
实际的代码有很多条形图的参数，例如标题，主题&注释，但我想他们不会妨碍输出。我使用的是汇总数据，其中代码中的 Freq 是特定术语的频率。当我寻求帮助时，我重复得到了对条形图使用 stat =identity的指示。
任何帮助都将不胜感激。

重申，

与此错误的解决方案。
您已经总结了 geom_bar（）的列。您需要将 stat = stat_count （默认在 geom_bar（））中更改为标识。
+ geom_bar（stat =identity）
或者，您可以使用 geom_col 。
In many of my programs I have been using ggplot2 to render charts. I have loaded them on shinyapps.io and they are working absolutely fine. However, when I try to run the program on my machine, i am getting the following error:
Error : stat_count() must not be used with a y aesthetic.
The following is the example code:
ggplot(hashtg, aes(x=reorder(hashtag, Freq), y = Freq, fill = hashtag)) + geom_bar(stat="identity") +
geom_bar(width = 0.4) + xlab("Hashtags Used") + ylab("Number of responses") +
geom_text(aes(label=Freq), hjust = 1, colour = "white" )
The actual code has many arguments of bar graph such as title, theme & annotation, but I guess they would not hamper the output. I am using aggregated data where Freq in the code is the frequency of a particular term. When I searched for help, I repeated get instructions to use stat = "identity" for a bar plot.
Any help would be highly appreciated.

To reiterate, the same code works without a trouble in shinyapps.io.
I found this link (http://tutorials.iq.harvard.edu/R/Rgraphics/Rgraphics.html) with the solution for this error.
The column you are trying to summarize with geom_bar() is already summarized. You need to change stat=stat_count (default in geom_bar()) to identity.
+ geom_bar(stat="identity")
Or, you can use geom_col instead.
