lty <- c("11", "18", "1f", "81", "88", "8f", "f1", "f8", "ff") linetypes <- data.frame( y = seq_along(lty), lty = lty ) ggplot(linetypes, aes(0, y)) + geom_segment(aes(xend = 5, yend = y, linetype = lty)) + scale_linetype_identity() + geom_text(ae...
This R graphics tutorial describes how to change line types in R for plots created using either the R base plotting functions or the ggplot2 package.
使用以下代码加载ggplot2包: library(ggplot2) 1. 创建ggplot对象,并设置x轴和y轴变量,同时设置linetype和shape参数为group变量。这里的data是数据集的名称,x和y是数据集中的两个变量名称,group是用于设置linetype和shape的变量名称。使用以下代码创建ggplot对象: ggplot(data,aes(x,y,linetype=group,shape=group))...
ggplot2: 是R语言中一个强大的绘图系统,基于Grammar of Graphics理论。 geom_line(): 在ggplot2中用于添加线条的几何对象。 aes(): aesthetics的缩写,用于映射数据到图形属性,如颜色、大小、形状等。 控制颜色的方法 直接指定颜色: 可以直接在geom_line()中通过color参数指定颜色。
Example 2: Adjust Color, Size & Linetype of Line Segment in ggplot2 Plot In this example, I’ll demonstrate how to change the color, size and linetype of our line segment. Consider the R code below: ggp+# Modify color, size & linetypegeom_segment(x=2.5, ...
ggplot2是一个用于数据可视化的R语言包,它提供了丰富的绘图功能。在直方图上添加多个垂直线(vline)可以用于标记特定的数值或者阈值。下面是使用ggplot2在直方图上添加多个vline的步骤:...
library(ggplot2)主要函数及参数 • Key functions: geom_line(), geom_step(), geom_path()• Key arguments to customize the plot: alpha, color, linetype and size.绘图数据 df <- data.frame(dose=c("D0.5", "D1", "D2"), len=c(4.2, 10, 29.5))head(df)df2 <- data.frame...
In this R programming tutorial, we’ll also have to install and load theggplot2 package: install.packages("ggplot2")# Install ggplot2 packagelibrary("ggplot2")# Load ggplot2 package Now, we can plot our data as follows: ggp<-ggplot(data,# Create ggplot2 boxplotaes(x=values, y=group)...
This article describes how to create a line plot using the ggplot2 R package. You will learn how to: 1) Create basic and grouped line plots; 2) Add points to a line plot; 3) Change the line types and colors by group.
ggplot(aes(date, value01, group = variable)) + geom_line(aes(colour = value01), linetype = 2) 2. 参考线 为图形添加参考线对图形的注释非常有用,主要有水平、竖直和对角线三种参考线,对应于三个函数: geom_hline:yintercept(y轴截距)
