r - .External.graphics R 中的错​​误

Question

我使用下面的函数从 48 列 X 32 行的矩阵创建热图:

heatmap.2(all.data,Rowv = FALSE, Colv = FALSE, trace="none",main="All data",col=colorRampPalette(c("green","yellow","red")))

由于删除了树状图，它给了我一些警告，但它仍然给了我想要的热图加上颜色键，发生了一些事情，现在当我尝试运行相同的东西时，它给了我没有颜色的图 key 和错误:

Error in plot.new() : figure margins too large
In addition: Warning messages:
1: In heatmap.2(all.data, Rowv = FALSE, Colv = FALSE, trace = "none",  :
  Discrepancy: Rowv is FALSE, while dendrogram is `both'. Omitting row dendogram.
2: In heatmap.2(all.data, Rowv = FALSE, Colv = FALSE, trace = "none",  :
  Discrepancy: Colv is FALSE, while dendrogram is `none'. Omitting column dendogram.

如果我将所有边的边距更改为 1:

par(mar=c(1,1,1,1))
heatmap.2(all.data,Rowv = FALSE, Colv = FALSE, trace="none",main="All data",col=colorRampPalette(c("green","yellow","red")))

然后再试一次，它不会生成热图并给我这个错误:

Error in .External.graphics(C_layout, num.rows, num.cols, mat, as.integer(num.figures),  : 
  invalid graphics state
In addition: Warning messages:
1: In heatmap.2(all.data, Rowv = FALSE, Colv = FALSE, trace = "none",  :
  Discrepancy: Rowv is FALSE, while dendrogram is `both'. Omitting row dendogram.
2: In heatmap.2(all.data, Rowv = FALSE, Colv = FALSE, trace = "none",  :
  Discrepancy: Colv is FALSE, while dendrogram is `none'. Omitting column dendogram.

我也尝试添加功能键=T，但颜色键仍然没有出现在热图中，任何帮助将非常感激!

如果您的绘图过去一直有效，但现在抛出无效图形状态错误，请尝试通过调用dev.off()来重置图形设备。这是 RStudio 帮助网站建议的。
