如何在heatmap.3中調整列標簽

Question

以下是我的heatmap.3代碼：

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)

我使用此代碼獲得以下熱圖：

我的問題是如何調整列標簽，使其不與熱圖重疊？

謝謝！

Answer 1

您可以將adjCol設置為居中對齊，將offsetCol設置為向下移動標簽：

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)
