如何使用Cowplot包在R中的同一页面上绘制多个图？

Question

I am using built-in data set iris in R, I want to plot several graphs on the same page for which I am using cowplot package.
However, the problem I face is that the labels in the figures i,e "A" and "B" overlap the y-axix. How can I lleave some space in between labels and y-axis? My code is:

View(iris)
library(tidyverse)

p1 <- ggplot(iris, aes(Sepal.Length, Petal.Length, col = Species))+geom_point()
p2 <- ggplot(iris, aes(Sepal.Length, Petal.Width, col = Species))+geom_point()
library(cowplot)
plot_grid(p1,p2, labels = c("(A)","(B)"))

Answer 1

You can try to work with the options of plot_grid , the default are these:

plot_grid(p1,p2, labels = c("(A)","(B)"), align = 'h', label_size = 12,
          label_x = 0, label_y = 1, hjust = -0.5, vjust = 1.5 )

For example, something like this:

plot_grid(p1,p2, labels = c("(A)","(B)"), align = 'h', label_size = 12,
          label_x = 0, label_y = 1, hjust = -0.1, vjust = 5 )
