打印没有行和列索引的矩阵 [英] Print a matrix without row and column indices

问题描述

如果我打印一个矩阵，它将在控制台中与行和列索引一起显示.例如

If I print a matrix, it is shown with row and column indices in the console. E.g.

> print(diag(3))
     [,1] [,2] [,3]
[1,]    1    0    0
[2,]    0    1    0
[3,]    0    0    1

如何抑制列和行索引? IE.像这样的东西:

How can I suppress the column and row indices? I.e. something like this:

> print(diag(3), indices=FALSE)
1    0    0
0    1    0
0    0    1

我可以看到cwhmisc程序包应包含printM函数来执行此操作

I can see that the cwhmisc package should contain a printM function to do this according to the documentation but it is not there when I load cwhmisc. Also, this seems like something you should be able to to in base R.

推荐答案

函数 base软件包中的prmatrix 可以解决此问题，它可以使用参数collab和rowlab:

prmatrix(diag(3), rowlab=rep("",3), collab=rep("",3))

 1 0 0
 0 1 0
 0 0 1
