Create a scatter plot: p <- ggplot(df, aes(wt, mpg)) + geom_point(color = 'red') + theme_classic(base_size = 10) Add text labels: # Add text annotations using ggplot2::geom_text p + geom_text(aes(label = rownames(df)), size = 3.5) ...
由于limits = c(1, 7),x坐标轴的长度跨度为单位6,所以mult = c(1,2) 就是向左扩张了1*6个单位长度,向右扩张了2*6个单位长度。 4. 同时调整mult和add系数 ggplot(mpg, aes(displ, hwy)) + geom_point() + geom_vline(xintercept = c(1,7),linetype="dashed") + scale_x_continuous(breaks=...

Utility functions that retrieve information from, remove elements of, and add text to a plot object created by ggplot2 - GitHub - statech/ggutils: Utility functions that retrieve information from, remove elements of, and add text to a plot object created
ggp + # Draw line to plot geom_hline(yintercept = 3.3)In Figure 3 it is shown that we have added a vertical line to our plot using the previous R code.Example 3: Add Vertical & Horizontal Lines to ggplot2 PlotIn Example 3, I’ll show how to add vertical and horizontal lines to...
This example illustrates how to show a panel box around our ggplot2 plot. For this, we can use the theme function and the panel.border argument as shown below:ggp + # Add panel border to ggplot2 plot theme(panel.border = element_rect(color = "#1b98e0", fill = NA, size = 10))...

Run `rlang::last_error()` to see where the error occurred. 1. 2. 解决方法: 参考: https:///tidyverse/ggplot2/issues/4513 不用加号了,直接另起一行,用ggsave即可。不要用ggplot(…) + ggsave(…)了 修正后的代码如下: > library(ggplot2) ...
