没有行名和列名的矩阵显示? [英] Matrix display without row and column names?

问题描述

我在 R 中有这个代码:

seq1 <- seq(1:20)mat <- 矩阵(seq1, 2)

结果是:

<块引用>

 [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10][1,] 1 3 5 7 9 11 13 15 17 19[2,] 2 4 6 8 10 12 14 16 18 20

R 是否可以选择禁止显示列名和行名，这样我就不会得到 [,1] [,2] 等等?

解决方案

如果你想保留维度名称而不是打印它们，你可以定义一个新的打印函数.

print.matrix <- function(m){write.table(format(m, justify="right"),row.names=F, col.names=F, quote=F)}>打印(垫子)1 3 5 7 9 11 13 15 17 192 4 6 8 10 12 14 16 18 20

I have this code in R:

seq1 <- seq(1:20)
mat <- matrix(seq1, 2)

and the result is:

     [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,]    1    3    5    7    9   11   13   15   17    19
[2,]    2    4    6    8   10   12   14   16   18    20

Does R have an option to suppress the display of column names and row names so that I don't get the [,1] [,2] and so on?

解决方案

If you want to retain the dimension names but just not print them, you can define a new print function.

print.matrix <- function(m){
write.table(format(m, justify="right"),
            row.names=F, col.names=F, quote=F)
}

> print(mat)
 1  3  5  7  9 11 13 15 17 19
 2  4  6  8 10 12 14 16 18 20
