这是对每个结果变量进行三次重复比较的数据框架(因此子倍数级别为12)
A tibble: 36 x 10
s .y. group1 group2 n1 n2 p p.signif p.adj p.adj.signif
* <chr> <chr> <chr> <chr> <int> <int> <dbl> <chr> <dbl> <chr>

2 E value new_value_for_8 new_value_for_4 25 25 0.929 ns 1 ns
3 E value new_value_for_6 new_value_for_4 25 25 0.948 ns 1 ns

5 F value new_value_for_8 new_value_for_4 25 25 0.738 ns 1 ns
6 F value new_value_for_6 new_value_for_4 25 25 0.501 ns 1 ns
7 G value new_value_for_8 new_value_for_6 25 25 0.808 ns 0.808 ns
8 G value new_value_for_8 new_value_for_4 25 25 0.101 ns 0.303 ns
9 G value new_value_for_6 new_value_for_4 25 25 0.161 ns 0.321 ns
10 H value new_value_for_8 new_value_for_6 25 25 0.964 ns 0.964 ns
我刚刚为三个重复度量中的每一个创建了一个包含12个元素的列表，其中包含相关统计信息，如下所示:
my_comparisons <- list(E = comparisons[1:3,],
F = comparisons[4:6,],
G = comparisons[7:9,],
H = comparisons[10:12,],
I = comparisons[13:15,],
J = comparisons[16:18,],
K =comparisons[19:21,],
L = comparisons[22:24,],
M = comparisons[25:27,],
N = comparisons[28:30,],
O = comparisons[31:33,],
P = comparisons[34:36,])
得到以下结果
[[E]]
# A tibble: 3 x 10
s .y. group1 group2 n1 n2 p p.signif p.adj p.adj.signif
<chr> <chr> <chr> <chr> <int> <int> <dbl> <chr> <dbl> <chr>
1 E value new_value_for_8 new_value_for_6 25 25 0.877 ns 1 ns
2 E value new_value_for_8 new_value_for_4 25 25 0.929 ns 1 ns
3 E value new_value_for_6 new_value_for_4 25 25 0.948 ns 1 ns
[[F]] .... and so on
既然你可以在信号列中看到，根据它，我把列表分成了一些常见的字体(例如P3, FCz, lpearly等)。我想使用一个迭代函数，如lapply()，一些循环或map()函数来自动创建这个列表。
Thanks in advance
