无法在aheatmap中调整行标签的大小

Question

我正在尝试使用NMF包中的aheatmap函数创建热图。以下是我的数据框的详细信息：

> dim(mirs)
[1] 249  10

> dput(head(mirs))
structure(list(Ctrl.1 = c(6.16181305031523, 7.1487208026042,

有249行＆amp;我的数据中有10列，但我只显示了使用head的顶行。当我更改 fontsize 时，列标签会相应地调整大小，但问题是行标签没有。无论我多少增加fontsize或cexRow值，它们在pdf中看起来都很小。有人可以建议如何增加行标签的大小？随附的是我的情节＆amp;正如你所看到的，我对cexRow＆amp;使用了相同的值。 cexCol但与col标签相比，行标签非常小。

Answer 1

行标签的计算字体大小确实存在问题。 这已经修复了。 请参阅：https://github.com/renozao/NMF/issues/38

以下内容应为您提供与height一起增加的行标签：

aheatmap(x = as.matrix(dat), scale = 'row', legend = F
        , main = 'Heatmap', filename = 'plot.pdf'
        , width = 5, height = 10)
