Question

我想在R中打印一个没有行号的列表。

我尝试了cat命令，但它不适用于列表。

有人有任何建议吗？

    GROUP    SEX INCOME STATE    n  mean
11       1   Male      1    AL  159 26.49
12       2 Female      1    AL  204 26.64
13       3   Male      2    AL  255 27.97
14       4 Female      2    AL  476 29.06

要使用的示例数据：

foo <- structure(list(GROUP = 1:4, 
                      SEX = structure(c(2L, 1L, 2L, 1L),
                                      .Label = c("Female", "Male"),
                                      class = "factor"),
                      INCOME = c(1L, 1L, 2L, 2L), 
                      STATE = structure(c(1L, 1L, 1L, 1L), .Label = "AL", 
                                        class = "factor"), 
                      n = c(159L, 204L, 255L, 476L), 
                      mean = c(26.49, 26.64, 27.97, 29.06)),
                 .Names = c("GROUP", "SEX", "INCOME", "STATE", "n", "mean"), 
                 class = "data.frame", row.names = 11:14)

Answer 1

你只想要论证row.names = FALSE吗？ E.g。

> print(foo, row.names = FALSE)
 GROUP    SEX INCOME STATE   n  mean
     1   Male      1    AL 159 26.49
     2 Female      1    AL 204 26.64
     3   Male      2    AL 255 27.97
     4 Female      2    AL 476 29.06

这是使用?print.data.frame方法。

Answer 2

这样的事情应该有效：

apply(l, 1, function(x){cat(x); cat("\n")})

R中没有行号的打印列表
