我正在使用heatmap.2生成一个热图
And I am generating a heatmap using heatmap.2
heatmap.2(expr001,main="\n331 Genes : P.adj<0.01",cexCol=0.9,tracecol=NULL,col="bluered")
我得到下面的图:
如何减小列的宽度?有什么建议吗?
How can I reduce the width of the columns? Any suggestions?
推荐答案
尝试使用pheatmap程序包.您可以在其中使用参数cellwidth和cellheight更方便地控制单元格的大小.即使您的绘图以这种方式变得太大而无法放入绘图窗口，也可以通过使用参数filename将其写入具有正确测量值的文件中.
Try pheatmap package. There you can control the size of the the cells more conveniently, with arguments cellwidth and cellheight. Even if your plot becomes too big this way and does not fit into the plotting window, then by using argument filename you can write it into file with correct measurements.
