With ggplot2, it's easy to: produce handsome, publication-quality plots with automatic legends created from the plot specificationsuperimpose multiple layers (points, lines, maps, tiles, box plots) from different data sources with automatically adjusted common scalesadd customizable smoothers that use ...
It is also possible to append multiple line segments to a ggplot2 plot.For this, it makes sense to define all the parameters of our lines in a data frame object first:data_lines <- data.frame(x = 2:4, # Create data for multiple segments y = c(4.5, 5, 2), xend = c(6, 8,...

Plotly与其他扩展一起工作，包括ggpackets和gghighlights。plot图并不总是包含静态版本中出现的所有内容(例如，在撰写本文时，它还不能识别ggplot2字幕)。但在快速交互性方面，这个软件包很难被超越。注意，plotly库还有一个与ggplot无关的函数plot_ly()，它使用的语法类似于ggplot的qplot():plot_ly(snowfall2000s, ...
ggplot(data, aes(x, y))+# Draw ggplot2 plotgeom_line()+geom_point() As shown in Figure 1, we created a line and point plot (i.e. a graph where the lines connect the points) using the ggplot2 package with the previously shown R syntax. ...
qplot()类似于R基本绘图函数plot(),可以快速绘制常见的几种图形:散点图、箱线图、 小提琴图、直方图以及密度曲线图。其绘图格式为: qplot(x, y=NULL, data, geom="auto") 1. 其中: x,y: 根据需要绘制的图形使用; data:数据集; geom:几何图形,变量x,y同时指定的话默认为散点图,只指定x的话默认为直方...
