ggordpoint()如何更改置信椭圆的线条粗细？

liuninghua521 commented 3 years ago

老师好，我想知道如何更改置信椭圆的线条粗细。我根据教程进行PCOA分析，可视化pcoares对象，但ggordpoint()貌似没有这个参数；我想使用yyplot中的的geom_ord_ellipse函数，但是我不知道如何将geom_ord_ellipse图层添加到pcoaplot上。麻烦老师解答。谢谢老师！

geom_ord_ellipse has been used in ggordpoint. You can use ellipse_linewd to adjust the width of the ellipse line, ellipse_lty to adjust the type of ellipse line using the development version. You can use remotes::install_github("YuLab-SMU/MicrobiotaProcess") to re-install it.

> library(MicrobiotaProcess)
> library(phyloseq)
> data(GlobalPatterns)
> subGlobal <- subset_samples(GlobalPatterns, SampleType %in% c("Feces", "Mock", "Ocean", "Skin"))
> pcares <- get_pca(subGlobal, method="hellinger")
> pcaplot <- ggordpoint(pcares, factorNames=c("SampleType", "SampleType"), ellipse=TRUE, ellipse_linewd=0.6, ellipse_lty=2, poinsize=2.8)
> pcaplot
