按平均值合并R中的多个数据框(混合数据类型)

I've done some research about this (here and here), but I haven't found what I actually want to achieve. The closest I've found to what I'm looking for is here, but the code doesn't seem to work or do what I desire. Besides, I found out that rbindlist has been deprecated in favour of bind_rows, but I haven't been able to use bind_rows to achieve what I want.

我有一个30个数据框的列表,每个数据框具有相同的行数和列数,以及相同的列数据类型(尽管每一列可以是连续的和分类的)。我想将它们合并为具有相同行和列数的单个数据框,但每个单元格是数据框列表中对应于连续,整数和分类列的30个单元格的均值/中位数/多数表决,分别。这是一个包含三个数据帧的示例:

df 1:

A       B       C
2.3     5       3
12      3       1
0.4     13      2


df_2:

A       B       C
4.3     23      1
1       7       2
0.4     10      2

df_3:

A       B       C
1.3      3      3
2.2      4      2
12.4     10     1

结果数据框将是这样的:

df_result:

A       B        C
2.63     5       3
5.06     4       2
4.4     10       2

结合每种数据类型的更合适方式的任何指导也将受到高度赞赏。
