❝本节来介绍一个基于「ggplot2」来绘制相关性矩阵的R包,完美兼容「ggplot2」语法；下面通过一个案例来简单介绍一下，具体请查看作者官方文档 ❞
https://github.com/r-link/corrmorant
安装并加载R包
代码语言：javascript复制library(tidyverse)
remotes::install_github("r-link/corrmorant")
library(corrmorant)
library(ggfx)
library(RColorBrewer)
案例一
代码语言：javascript复制corrmorant(drosera, style = "light")
corrmorant(drosera, style = "dark")
corrmorant(drosera, style = "blue_red")
❝如果只是简单的需求那么通过上述代码也许就能满足我们的需求，但是如果要进行更加深入的图形修改那么就要兼容「ggplot2」语法，在此作者引入了一个新的函数「ggcorrm」 ❞
ggcorrm可视化相关性矩阵
代码语言：javascript复制mtcars %>% select(-vs,-am,-gear,carb) %>%
ggcorrm(.,aes(col = .corr, fill = .corr))
lotri(geom_jitter(alpha = 0.8, width = 0.5, height = 0.5))
with_outer_glow(lotri(geom_smooth(method = "lm",col = "goldenrod2")),
sigma=1)
utri_heatmap(alpha = 0.4)
utri_corrtext(size = 5)
dia_histogram(lower = 0.3, bins = 5, fill = "grey", alpha = 0.8)
dia_names(y_pos = 0.3, size = 4)
scale_color_gradientn(colours = RColorBrewer::brewer.pal(11,"RdBu"))
scale_fill_gradientn(colours = RColorBrewer::brewer.pal(11,"RdBu"))
scale_x_continuous(n.breaks = 4)
theme(legend.position = "none",
axis.text = element_text(size = 8,color="black"))
❝除了上述介绍外,「corrmorant」还支持用卡通头像来进行相关性的展示，只需修改对应的Unicode字符即可 ❞
卡通版相关性热图
代码语言：javascript复制airquality %>%
ggcorrm()
lotri_heatpoint(pch = "U1F63E")
utri_heatpoint(pch = "U2620", col = "#660066")
dia_names(y_pos = 0.15, size = 3)
dia_density(lower = 0.3, fill = "#89DFA3", color = 1)
scale_size(range = c(1, 15))
scale_color_corr(option = "C")
更多的Unicode字符可通过以下网址获取对应的编号,感觉还是蛮有趣的

代码语言：javascript复制airquality %>%

utri_heatpoint(pch = "U1F913", col = "#660066")
dia_names(y_pos = 0.15, size = 3)
dia_density(lower = 0.3, fill = "#89DFA3", color = 1)
scale_size(range = c(1, 15))
scale_color_corr(option = "C")
