如何在heatmap中更改顏色鍵高度

Question

我試圖減少熱圖的大小.2顏色鍵

現在是這樣的

key=T,  # add the key color
key.title =NA,
cexRow = 0.75, 
cexCol=0.75,

我想減少它的高度，變成這樣

這就是我繪制熱圖的方法

heatmap.2(mat_data,
          key=T,  # add the key color
          key.xlab="label",
          key.title =NA,
          cexRow = 0.75, 
          cexCol=0.75,
          #lhei = c(5,5),
          #cellnote = mat_data,  # will display the values 
          main = "title to be shonwn ", # heat map title
          #notecol=NA,          # change font color of cell labels to black
          density.info="none",  # turns off density plot inside color legend
          trace="none",         # turns off trace lines inside the heat map
          margins =c(15,20),     # widens margins around plot
          col=myPalette,       # use on color palette defined earlier
          breaks=col_breaks,    # enable color transition at specified limits
          dendrogram="row",     # only draw a row dendrogram
          Colv="NA",
          notecex=1.0)  

我找到

密鑰大小= 1

您可以根據需要調整大小來改變大小

Answer 1

可以使用heatmap.2()的lhei參數進行設置

heatmap.2(data,lhei = c(1,7))

參數是長度為2的向量，並且看起來是鍵和熱圖的相對高度。
