Print a matrix without row and column indices
10
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
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
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.

The function prmatrix in the base package could work for this, it can take the arguments collab and rowlab:
prmatrix(diag(3), rowlab=rep("",3), collab=rep("",3))

This adds space at the top and the left side though. The output is the same as form <- diag(3); colnames(m) <- rownames(m) <- rep("", 3); print(m).

The documentation seems to be out of date: it referencesprint.matrixbut there doesn't appear to be any such print method in current R versions.

Thanks! I chose this answer overwrite.tablebecause it keeps columns aligned and I do have characters in my matrix. Manually specifyingrowlabandcollabis ugly though and I tried outwrite.tablein combination withprint(...., gap=3)for this reason but couldn't get it to work. Usingprmatrix(my_matrix, rowlab=rep("", nrow(my_matrix), collab=rep("", ncol(my_matrix))is nicer for future copy-and-paste :-) You're welcome to update your answer with this.

Another solution with function write.table
write.table(diag(3), row.names=F, col.names=F)
You can make it prettier by separating the columns with a tabulation
write.table(matrix(sample(1000,9),3,3), row.names=F, col.names=F, sep="t")
