A grouped barplot display a numeric value for a set of entities split in groups and subgroups. Before trying to build one, check how to make a basic barplot with R and ggplot2. A few explanation about the code below: input dataset must provide 3 columns: the numeric value (value), an...

在SCI论文的数据图表中,作者习惯于用条形图来表示分类数据的分布特征。在ggplot2中,条柱对应的几何对象函数为geom_bar(), 它的功能就是展示计数数据,即每种分类水平一共有多少个观测值。 条形图示例 条形图分类 在ggplot2中,通常使用的条柱排列方式有三种,并排式(dodge)、堆栈式(stack)和填充式(fill)。
ggplot(test, aes(x = goterms, y = number, fill = group)) + ## 1. 按照输入数据的列名映射数据 geom_bar(position="stack",stat="identity") + ## 2. 排列方式,stack堆叠,换dodge变单独两条 coord_flip() + ## 3. 横竖转换,去掉这行就是竖排 ...

Part of R Language Collective 68 I was working on doing a horizontal dot plot (?) in ggplot2, and it got me thinking about trying to create a horizontal barplot. However, I am finding some limitations in being able to do this. Here is my data: df <- data.frame(Seller=c("Ad",...
