如何使用“stat_cor”function 更改 p.value 的大小？

Question

我正在嘗試更改圖形上R2和p.value的大小，例如在修改stat_cor function 時，但我在 R 中還不夠好，無法實現我的目標。 有沒有可能得到一些幫助？

非常感謝，祝您有美好的一天。 卡琳娜

sp <- ggscatter(IFNA, x = "OMsurClay_PH_s_A", y = "OMsurclay_PH_d_A",add = "reg.line",  
add.params = list(color = "blue", fill = "lightgray"), conf.int = TRUE,)

# pour le r2
sp2<- sp + stat_cor( aes(label = paste(..rr.label.., ..p.label.., sep = "~`,`~")),label.x = 0.5, method = "spearman",label.sep = "\n")
sp3<- sp2 + theme(text=element_text(size=16,color="black"),axis.text=element_text(size=16,color="black"),axis.title.x = element_text(face= "bold", size= 16),axis.title.y = element_text(face= "bold", size= 16))
sp3 +labs( x ="OM_OM/Clay_pH_s_A", y = "OM_OM/Clay_pH_d_A")

Answer 1

stat_cor 采用其他 arguments 傳遞給 geom_text 或 geom_label，包括“大小”和“顏色”，因此您可以像這樣更改命令：

stat_cor( aes(label = paste(..rr.label.., ..p.label.., sep = "~`,`~")),label.x = 0.5, method = "spearman",label.sep = "\n", size = 10)

Answer 2

您可以添加 cor.coef.size =

sp <- ggscatter(IFNA, x = "OMsurClay_PH_s_A", y = "OMsurclay_PH_d_A",add = "reg.line",
add.params = list(color = "blue", fill = "lightgray"), conf.int = TRUE, cor.coef.size = 7)
