【问题描述】:
这个问题与这个问题类似:R: Sum column wise value of two/more data frames having same variables (column names) and take Date column as reference,但我的 dfs 有不同的列数、列名并且没有特定的参考列。
修改他的例子:
df1:
V1 V2 V3
2 4 5
3 5 7
df2:
V1 V5 V2 V4
2 4 4 5
3 0 5 7
我想要的结果是:
df3:
V1 V2 V3 V4 V5
4 8 5 5 4
6 10 7 7 0
我不断收到如下错误:
Error: Problem with `mutate()` input `..1`.
✖ Input `..1` can't be recycled to size 28. # 28 because this is referring to my df
ℹ Input `..1` is `colnames(col_name)`.
ℹ Input `..1` must be size 28 or 1, not 5992.
Run `rlang::last_error()` to see where the error occurred.
我尝试过合并、加入、...等
