我正在用
fviz_pca_biplot
做 PCA 并想删除我的点的 ID 以使 PCA 更清晰。我想保留我的矢量标签。
删除ID应该用什么命令?
这是我的代码和结果。
pca_biplot = fviz_pca_biplot(res.pca, repel = TRUE, max.overlaps=Inf,
col.var = "#000000", # Variables color #colour of the lines
#colour = Population, #sets the colour of the data to be determined by population
axes = c(3, 4), # choose PCs to plot
habillage = data$Population,
col.ind = "#696969", #colour of points
labels=NULL
)
pca_biplot +
labs(title ="ACP", x = "CP3 (15,3%)", y = "CP4 (9,6%)") +
scale_color_manual(values = c("blue","red")) +
theme_minimal()
我也写了更详细的图例,但我无法删除初始标签。我打算简单地用白色方块遮住它,但是有没有办法只保留我定制的图例?
