我有一个数据集,我在其中手动为行名分配了一些 unicode(vars下面我的数据示例中的列):

在此处输入图像描述

我将此数据读入 R,将其转换为矩阵,vars列设置为矩阵的行名,然后使用complexheatmap包绘制热图 - 但是,它不接受我添加到行名的 unicodes,相反,我得到了这个:

Heatmap(data, name = "log p-value", column_title = "Sets", 
         row_title = "Vars", 
         column_names_rot = 45,
         cluster_rows = TRUE, cluster_columns = FALSE, col = col_fun)
Warning messages:
1: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y,  : conversion failure on 'var1�' in 'mbcsToSbcs': dot substituted for <e0>
2: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y,  : conversion failure on 'var2�' in 'mbcsToSbcs': dot substituted for <e0>
3: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y,  : conversion failure on 'var3�' in 'mbcsToSbcs': dot substituted for <e0>
4: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y,  : conversion failure on 'var4�' in 'mbcsToSbcs': dot substituted for <a0>

然后,对于带有 unicode 的行名,输出图为空白。我怎样才能让这个热图接受行名中的 unicode?到目前为止,我只发现了类似的问题,这些问题集中在 ggplot 上,而不是使用其他包,如 complexheatmap。任何帮助或指导表示赞赏。

编辑:尝试添加示例代码,但是当我直接从 R 中获取它时,它不允许我包含 unicode,因为它们实际上在上图中看起来(例如 †、‡):
