ggplot2使用数字及字符串预定义好了几种线型,可以直接使用。 0 = "blank" 1 = "solid" 2 = "dashed" 3 = "dotted" 4 = "dotdash" 5 = "longdash" 6 = "twodash" lty <- c("solid", "dashed", "dotted", "dotdash", "longdash", "twodash") linetypes <- data.frame( y = seq_along...
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.

在ggplot2中,可以使用不同的方法来消除geom_line中不需要的部分。 一种常见的方法是使用geom_path()代替geom_line()。geom_path()会连接数据点,但不会在数据...
首先,我们需要加载ggplot2包,该包提供了创建各种图表的功能。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...
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和灵活的图形定制选项。在ggplot2中,axis.line主题用于控制轴线的绘制。 axis.line主题可以用于以下目的: 轴线的连接:axis.line可以控制轴线是否连接到原点。当axis.line为TRUE时,轴线会连接到原点;当axis.line为FALSE时,轴线不会连接到原点。 axis.line...
In the graphs below, line types and point shapes are controlled automatically by the levels of the variablesupp: p <- ggplot(df2, aes(x = dose, y = len, group = supp))# Change line types and point shapes by groupsp + geom_line(aes(linetype = supp)) + ...
Let’s assume that we want to create a ggplot2 barchart with a line on top, where the bars represent the sample column and the line represents the responses column. In order to use the functions of theggplot2 package, we also need to install and load ggplot2. ...
