在R中使用ggplot为timeplot绘制多条线,可以通过以下步骤实现: 1. 首先,确保已经安装了ggplot2包。如果没有安装,可以使用以下命令进行安装: ```R install.pack...
# Scatter Plot library(ggplot2) ggplt <- ggplot(Orange,aes(x=circumference,y=age))+ geom_point()+ theme_classic() ggplt # Plotting a single Regression Line ggplt+geom_smooth(method=lm,se=FALSE,fullrange=TRUE) R Copy输出这是一个单一的平滑线,或俗称为回归线。在这里,各点是结合在一起...

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, x = ~Winter, y = ~Total, type = “bar”)原文：ggplot2 is not only the R language’s most popular data visualization package, it is also an ecosystem. Numerous add-on packages ...
Line plot of the variable ‘psavert’ by date: ggplot(data = economics, aes(x = date, y = psavert))+ geom_line() Plot with multiple lines Well plot both ‘psavert’ and ‘uempmed’ on the same line chart. Solution 1: Make two calls togeom_line(): ...
ggplot2是由Hadley Wickham创建的一个十分强大的可视化R包。按照ggplot2的绘图理念,Plot(图)= data(数据集)+ Aesthetics(美学映射)+ Geometry(几何对象): data: 数据集,主要是data frame; Aesthetics: 美学映射,比如将变量映射给x,y坐标轴,或者映射给颜色、大小、形状等图形属性; ...
