在R 3.01中更改簇树状图的标签大小 [英] Change label size of Cluster Dendrogram in R 3.01

问题描述

有人发现R 3中明显的错误的变通办法，该错误禁止更改簇树状图上的标签大小吗?

Has anybody found a workaround to the apparent bug in R 3 which prohibits changing the label size on a Cluster Dendrogram?

以下代码在将R更新到3.01之前可以正常工作(我认为以前的版本是2.15):

The following code used to work fine before updating R to 3.01 (prior version was 2.15 I think):

plot(hclust, labels = data[, 1], cex = 0.3)

现在，更改cex参数时，标签大小没有变化.

Now there is no change to label size when altering the cex argument.

推荐答案

在调用plot()之前，可以使用par()函数设置cex参数.例如:

You could set the cex parameter using the par() function before the call to plot(). For example:

# example from ?hclust
hc <- hclust(dist(USArrests), "ave")

# default label size
plot(hc, xlab="xlab", ylab="ylab", main="main", sub="")

# reduced label size
par(cex=0.3, mar=c(5, 8, 4, 1))
plot(hc, xlab="", ylab="", main="", sub="", axes=FALSE)
par(cex=1)
title(xlab="xlab", ylab="ylab", main="main")
axis(2)
