R中的照片地图格式:图例大小并创建一个正方形图 [英] pheatmap formatting in R: Legend size and creating a square plot

问题描述

仅当Legend = FALSE时，热图才会创建正方形图.我尝试使用par()允许更多的oma()和mar()空间而没​​有运气.传说也确实很大，我找不到减少或改变其位置的任何文档.第一个图未安装树状图，但这与尺寸问题无关.无论群集如何，都会发生相同的情况.我将不胜感激

Pheatmap only creates a square plot when legend=FALSE. I have tried using par() to allow more oma() and mar() space without luck. The legend is also really big and i cannot find any documentation on reducing this or changing its position. The first plot doesn't have a dendrogram fitted but this is irrelevant to the sizing issue. The same happens regardless of the clustering. I would appreciate any comments

png(filename="tmpfile.png", width=1500, height=1500, res=500)
pheatmap(res, cluster_rows=FALSE, cluster_cols=FALSE, main="Default_clust", annotation=res2, color = rainbow(n, start=.7, end=.1), show_rownames=FALSE, show_colnames=FALSE, border_col=NA, fontsize=6)
dev.off()

推荐答案

关于平方图的问题实际上与绘制Pearson相关性非常相关.我来这里是为了寻求答案，最后我想出了一种解决方法，可以手动设置像元宽度，例如:

The question about square plot is actually quite relevant for plotting Pearson correlations. I came here hoping for an answer, in the end I came up with a workaround to set the cell width manually, eg:

pheatmap(...,     
cellheight=3, cellwidth = 3)

但是我想要一个更好的方法.

But I would like a better way.
