theme(legend.position = c(0.1, 0.33), legend.title = element_blank(),
legend.background = element_rect(fill = "white", color = "black"))
生成此图的对象：
我想将图例分成两列，每列 7 个元素。我试过 guides(fill=guide_legend(ncol=2)) 但它没有修改任何东西。也许我把它放在了错误的地方，或者它可能是实现这一目标的另一种方式。有人可以帮忙吗？
非常感谢
你从不把fill=定义为审美；请改用 guides(color=...)。
注意：使用此示例数据，我需要向 scale_color_manual 添加另一种颜色；您的真实数据不需要它。我要添加到您的代码中的唯一更改是 guides.
的一个参数
ggplot(Cat_urine, aes(x=UMAP1, y=UMAP2, color=colors)) +
geom_point(size=5) +

guides(
colour = guide_legend(ncol = 2, override.aes = list(size=5))
## ^^^^^^ ^^^^^^^^ these are the changes
) +
ylim(c(-7,5)) + xlim(c(-5,2.5)) + guides(shape = guide_legend(override.aes = list(size = 4))) +

theme(legend.position = c(0.1, 0.33), legend.title = element_blank(),

当然，您需要调整图例位置...

以及以下 ggplot2 代码：
ggplot(Cat_urine, aes(x=UMAP1, y=UMAP2, color=colors)) +
geom_point(size=5) +
scale_color_manual(labels = c("Urine","Brain", "Colon", "Duodenum", "Jejunum", "Ileum", "Plasma", "Heart", "Skeletal muscle", "Skin",

guides(colour = guide_legend(override.aes = list(size=5))) +
ylim(c(-7,5)) + xlim(c(-5,2.5)) + guides(shape = guide_legend(override.aes = list(size = 4))) +
theme_bw() + theme(axis.text.x = element_text(size=10), axis.title=element_text(size=12),
axis.text.y =element_text(size=10),plot.margin = margin(1, 0.5, 0.5, 1, "cm")) +
xlab("\nComponent 1") + ylab("Component 2\n") +
theme(legend.position = c(0.1, 0.33), legend.title = element_blank(),
legend.background = element_rect(fill = "white", color = "black"))
生成此图的对象：
我想将图例分成两列，每列 7 个元素。我试过 guides(fill=guide_legend(ncol=2)) 但它没有修改任何东西。也许我把它放在了错误的地方，或者它可能是实现这一目标的另一种方式。有人可以帮忙吗？
非常感谢
你从不把fill=定义为审美；请改用 guides(color=...)。
注意：使用此示例数据，我需要向 scale_color_manual 添加另一种颜色；您的真实数据不需要它。我要添加到您的代码中的唯一更改是 guides.

当然，您需要调整图例位置...
