当我使用“as.dendrogram”绘制树形图时,所有叶标签都被切割。请参阅以下链接图片作为示例:
当我使用“hclust”(所有标签正确显示)Dendrogram 1绘图
当我使用“as.dendrogram”Dendrogram 2绘图
代码:
我创建的数据只是为了显示问题
test <- matrix(c(34,34,32,27,12,1,2,1,1,1), ncol=2)
colnames(test) <- c('Variable1', 'Variable2')
rownames(test) <- c('African Forest Elephant', 'Asian Domestic Elephant','African White Rhino','West African Giraffe','African Mountain Gorilla')
test_table <- as.table(test)
绘制第一个链接图像
hctest = hclust(dist(test_table))
plot(hctest, axes = FALSE)
第二个
hctest = as.dendrogram(hctest)
plot(hctest, edge.root = TRUE, horiz = TRUE)
PS:如果我使用“horiz = FALSE”,同样的问题仍然存在。我尝试导出图像,并尝试使用R降价,但没有任何变化。
您可以通过调整绘图边距par
来修复mar=c(bottom, left, top, right)
。 (默认值为c(5, 4, 4, 2) + 0.1
)。
par(mar=c(5, 4, 4, 10) + 0.1)
plot(hctest, edge.root=TRUE, horiz=TRUE)
