使用R中的cophyloplot绘制具有尽可能多的水平链接的镜像树

我在cophyloplot的{​​{1}}包中使用ape来制作两个与链接面对面的系统发育树(树根植于提示1)。

R

但是,如果我旋转一些节点,则可以操纵一棵树,以便更多链接显示为水平/直线(即树更加镜像)。

有没有办法自动绘制带有链接的树,以便默认情况下它们是彼此最佳匹配/镜像?即尽可能多的链接是水平的?

编辑:是否还有统计测量树木的相似程度?或者是library(ape) set.seed(1) tree1 <-read.nexus("tree1.nex", tree.names = NULL) tree2 <-read.nexus("tree2.nex", tree.names = NULL) tree1$tip.label<-(1:28) tree2$tip.label<-(1:28) a <- c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28) b <- c(1,15,3,4,6,5,23,26,28,27,16,14,22,18,19,10,9,8,7,11,25,24,2,21,12,13,17,20) association <- cbind(a, b) cophyloplot(tree1, tree2, assoc = association, length.line = 4, space = 30, gap = 3,col="red", show.tip.label=FALSE) 给出的?

“最佳拟合”可以使用 R 包 phytools 直接可视化。

使用 from django.db import models from django.conf import settings from django.contrib.auth.models import AbstractUser, BaseUserManager from django.utils.translation import ugettext_lazy as _ class UserManager(BaseUserManager): """Define a model manager for User model with no username field.""" pass class CustomUser(AbstractUser): """Model representing a User with some extended fields and email as username field""" username = None email = models.EmailField(max_length=100, unique=True) is_admin = models.BooleanField(default=False) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] class Meta: ordering = ['email'] db_table = 'users' objects = UserManager() def __str__(self): """String for representing the Model object.""" return self.email class Group(models.Model): """Model representing a Group""" name = models.CharField(max_length=200) members = models.ManyToManyField(settings.AUTH_USER_MODEL, through='UserGroup', related_name='user_groups') class Meta: ordering = ['name'] db_table = 'groups' def __str__(self): return self.name class UserGroup(models.Model): """Model representing a User's Group""" group = models.ForeignKey(Group, on_delete=models.CASCADE, verbose_name = 'group') user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, verbose_name = 'user') class Meta: db_table = 'user_groups' 函数(其作用与 apecophylo() 相同)并将旋转设置为 TRUE。
