If I print a matrix, it is shown with row and column indices in the console. E.g.
如果我打印矩阵,它将在控制台中显示行和列索引。例如。
> print(diag(3))
[,1] [,2] [,3]
[1,] 1 0 0
[2,] 0 1 0
[3,] 0 0 1
How can I suppress the column and row indices? I.e. something like this:
如何抑制列和行索引?即像这样的东西:
> print(diag(3), indices=FALSE)
1 0 0
0 1 0
0 0 1
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.
我可以看到cwhmisc包应该包含一个printM函数来根据文档执行此操作,但是当我加载cwhmisc时它不存在。此外,这似乎是你应该能够在基地R的东西。

The function prmatrix
in the base
package could work for this, it can take the arguments collab
and rowlab
:
基础包中的函数prmatrix可以为此工作,它可以采用参数collab和rowlab:
prmatrix(diag(3), rowlab=rep("",3), collab=rep("",3))
1 0 0
0 1 0
0 0 1

Another solution with function write.table
另一个函数write.table的解决方案
write.table(diag(3), row.names=F, col.names=F)
You can make it prettier by separating the columns with a tabulation
您可以通过使用制表分隔列来使其更漂亮
write.table(matrix(sample(1000,9),3,3), row.names=F, col.names=F, sep="\t")
