我知道如何将彩色条形图添加到树状图中,但当我设置horiz=T时,条形图绘制在错误的轴上。
树枝状延伸简介中的示例显示了如何在绘图中添加彩色条:
dend15 <- c(1:5) %>% dist %>% hclust(method = "average") %>% as.dendrogram
is_odd <- ifelse(labels(dend15) %% 2, 2,3)
is_345 <- ifelse(labels(dend15) > 2, 3,4)
is_12 <- ifelse(labels(dend15) <= 2, 3,4)
k_3 <- cutree(dend15,k = 3, order_clusters_as_data = FALSE)
# The FALSE above makes sure we get the clusters in the order of the
# dendrogram, and not in that of the original data. It is like:
# cutree(dend15, k = 3)[order.dendrogram(dend15)]
the_bars <- cbind(is_odd, is_345, is_12, k_3)
the_bars[the_bars==2] <- 8
dend15 %>% plot(horiz=F)
colored_bars(colors = the_bars, dend = dend15)
当我执行上面的代码时,我看到了这个图:
彩色条形图是的好例子
但是,当我键入时
dend15 %>% plot(horiz=T)
colored_bars(colors = the_bars, dend = dend15)
这就是我看到的:
彩色条形图不良示例
是否可以将彩色条移动到树的叶节点旁边的轴上?
也许这段代码(取自此处)可以帮助您:
par(mar = c(4,1,1,12))
plot(dend15, horiz = TRUE)
colored_bars(dend15, colors = the_bars, horiz = TRUE)
祝你好运!
