删除轴标签后如何使 R 图居中

我正在研究 R 中的矩阵可视化（几乎与 http://reference. Wolfram.com/mathematica/ref/MatrixPlot.html），我一直用它

image(<matrix>,axes=FALSE)

来绘制图片。然而，我注意到，当 y 轴关闭时，绘图并不居中——轴刻度 + 标签的空间仍然存在。我可以欺骗一些居中，

par(oma=c(0,0,0,2.5))

但这似乎效率低下且容易出错（如果我的矩阵要改变尺寸/变得非正方形）。有没有更好的方法来强制图形居中？参考图片 http://img694.imageshack.us/img694/9891/metropolis.png< /a>

右侧边距明显小于左侧。

I'm working on visualizing a matrix in R (almost exactly like http://reference.wolfram.com/mathematica/ref/MatrixPlot.html), and I've been using

image(<matrix>,axes=FALSE)

to draw the picture. However, I noticed that with the y-axis turned off, the plot isn't centered--the space is still there for the axis ticks + label. I can finagle some centering with

par(oma=c(0,0,0,2.5))

but this seems inefficient and error-prone (if my matrix were to change dimensions/become non-square). Is there a better way to force the graphic to center?

The right hand margin is significantly smaller than the left.
