在使用geom_mark参数之前,我们首先需要创建一个基本的图形,例如散点图或折线图。接下来,我们可以通过以下步骤来使用geom_mark参数: 1.选择要标记的数据点或区域:首先,我们需要确定要标记的数据点或区域。这些数据点或区域可以是具有特定特征的数据,例如异常值、极值或关键转折点。 2.确定标记的类型:接下来,我们需要...
geom_mark_ellipse实际上是用于注解的，因为默认情况下它会将椭圆扩展5mm，并允许在每个椭圆内添加标签。...
同事提出让注释“支棱”起来，首先想到的是ggforce中的geom_mark_ellipse，实践中遇到一些问题（比如，...
geom_mark_ellipse中的椭圆只是画出一个尽可能小的椭圆,可以包围每组中的点。正如帮助文件所述: 使用Khachiyan算法估计包围椭圆 Khachiyan算法是一种确定可以包围一组点的最小体积椭球的方法,在二维空间(如双平面图)中,这意味着可以覆盖所有点的最小椭圆。 geom_mark_ellipse实际上是用于注释的,因为默认情况下,它...
geom_point() + stat_summary(fun.data = "n_mean_fun", geom = "text", color = "black") ``` 以Rmarkdown html输出运行时的绘图: 作为Rshing文档运行时的结果: --- title: "test" author: "Ronan Brady" date: "2023-08-08" output: ...

We introduce the shape module of the Python package Geomstats to analyze shapes of objects represented as landmarks, curves and surfaces across fields of natural sciences and engineering. The shape module first implements widely used shape spaces, such as the Kendall shape space, as well as elas...
m. scutellata (N = 12)), using geometric morphometric analysis, based on 19 landmarks on the left forewings of workers. The analysis allowed separating size and shape of the wing. Hierarchical cluster analysis followed by stepwise discriminant analysis (DA) grouped the colonies into two morpho...
I am using ggplot and geom_point to plot various data points. I am classifying points according to two thresholds and would like to add vertical lines to indicate where these thresholds are with respect to the points. However, the lines are not in the correct place. After...
