如何调整heatmap中的列标签

Question

以下是我对heatmap.3的代码：

heatmap.3(x = as.matrix(res), dist.FUN = dist2, scale = 'row', color.FUN = col_ylgnbu, 
                           cex.main = 2, trace = 'none', srtCol = 45, adjCol = c(1,0.1),
                           main = paste(title), 
                           key = T, cexRow = 2, cexCol = 1)

我使用以下代码获得以下热图：

我的问题是如何调整列标签以使它们不与热图重叠？

谢谢！

您可以将 adjCol 设置为居中对齐， offsetCol 可以将标签向下移动：

heatmap.3(x = as.matrix(res), dist.FUN = dist2, scale = 'row', 
    color.FUN = col_ylgnbu, 
    cex.main = 2, trace = 'none', srtCol = 45, 
    adjCol = c(1,0), offsetCol=1
    main = paste(title), 
    key = T, cexRow = 2, cexCol = 1)
