我的 plot_grids 在 R 中使用 cowplot 和 ggplot2 缺少网格中的四个图之一？
My plot_grids using cowplot in R with ggplot2 are missing one of the four plots in the grid?
很抱歉我发布了多少代码，但我缺少使用 plot_grid 包 cowplot 的四个 ggplots 之一，网格中应该有四个，出于某种原因一个其中缺少了，有人知道为什么吗？
这是缺少四个图表之一的 plot_grid：
这是错误：

我尝试添加 title_theme 但出现错误 object 'title_theme1' not found:
title_theme1 <- ggdraw() +
draw_label("ANN Models with 02 Learning Rate",
fontfamily = theme_georgia()$text$family,
fontface = theme_georgia()$plot.title$face, x = 0.05, hjust = 0)
plot_grid(title_theme, gridded, ncol = 1, rel_heights = c(0.2, 1))
title_theme2 <- ggdraw() +
draw_label("ANN Models with 08 Learning Rate",
fontfamily = theme_georgia()$text$family,
fontface = theme_georgia()$plot.title$face, x = 0.05, hjust = 0)
plot_grid(title_theme, gridded, ncol = 1, rel_heights = c(0.2, 1))
#plot_grid(plot3_02, plot10_02, plot20_02, plot50_02 + rremove("x.text"),
plot_grid(title_theme1, plot3_02, plot10_02, plot20_02, plot50_02, labels = c("N3", "N10", "N20", "N50"), ncol = 2, nrow = 2)
plot_grid(title_theme2, plot3_08, plot10_08, plot20_08, plot50_08, labels = c("N3", "N10", "N20", "N50"), ncol = 2, nrow = 2)
这是一个例子：
library(tidyverse)
library(palmerpenguins)
library(cowplot)
p1 <- penguins %>%
na.omit() %>%
ggplot(aes(x = bill_length_mm, y = body_mass_g)) +
geom_point() +
theme_bw(base_size = 14) +
labs(x = "Bill Length (mm)",
y = "Body Mass (g)")
p2 <- penguins %>%
na.omit() %>%
ggplot(aes(x = factor(species), y = body_mass_g)) +
geom_boxplot(outlier.shape = NA) +
geom_jitter(aes(color = species),
show.legend = FALSE,
width = 0.25,
alpha = 0.4,
size = 3) +
theme_bw(base_size = 14) +
labs(x = "Species",
y = "Body Mass (g)")
p3 <- penguins %>%
na.omit() %>%
ggplot(aes(x = bill_depth_mm, y = body_mass_g)) +
