在ggplot中,可以使用geom_text()函数来添加文本标签到piechart的外部。 具体步骤如下: 导入ggplot包:在R中使用library(ggplot2)命令导入ggplot包。 准备数据:准备一个包含分类和对应数值的数据集。 创建饼图:使用ggplot()函数创建一个基础的饼图对象,并设置数据集和分类变量。 添加饼图层:
library(ggplot2) # Barplot bp<- ggplot(df, aes(x="", y=value, fill=group))+ geom_bar(width = 1, stat = "identity") bp Create a pie chart : pie <- bp + coord_polar("y", start=0) pie Change the pie chart fill colors ...
Pie charts are the classic choice for showing proportions for mutually-exclusive categories. We'll show you how to use ggplot2 package to create a basic pie chart in R.
> pie <- ggplot(df, aes(x = "", y=freq, fill = factor(class))) + + geom_bar(width = 1, stat = "identity") + + theme(axis.line = element_blank(), + plot.title = element_text(hjust=0.5)) + + labs(fill="class", + x=NULL, + y=NULL, + title="Pie Chart of class"...

1、R包版本问题 相信很多人都会遇到这个问题。如“这个R包版本不适用于该版本R”、“连接错误”、“依赖包安装无效或版本不足”等等。这时候通常解决办法两种: (1)重装R和Studio,但这样就显得过于麻烦了。 (2)相信第二种办法很多人就愿意去尝试了。一个是利用R官网提供的R包下载路径,通过自己下载tar.zip文件导...
