没有行和列名称的矩阵显示?
问题描述：
我在R中有以下代码:
seq1 <- seq(1:20)
mat <- matrix(seq1, 2)
结果是:
[,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是否可以禁止显示列名和行名，这样我就不会得到[，1] [，2]等?
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?
答
如果要保留尺寸名称但不打印尺寸名称，则可以定义新的打印功能.
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
