Answer 1

错误很明显 - replacement has 64 rows, data has 999 。

这意味着在你的代码中的某个地方（我不能告诉你在哪里，因为你没有发布它）你试图只替换对象的一部分。

以下是您尝试执行的操作的示例，基于一些示例数据：

# Make a dataframe with 10 rows in it
df = data.frame(A = 1:10, B = 1:10+1)
df
#>     A  B
#> 1   1  2
#> 2   2  3
#> 3   3  4
#> 4   4  5
#> 5   5  6
#> 6   6  7
#> 7   7  8
#> 8   8  9
#> 9   9 10
#> 10 10 11

如果您尝试分配具有不同长度向量或一组值的行之一，则会出现错误。

df$A = c(1,2,3)
#> Error in `$<-.data.frame`(`*tmp*`, A, value = c(1, 2, 3)): replacement has 3 rows, data has 10

如果您尝试将列更改为等长的向量，它将起作用。

df$A <- c(1,1,1,1,1,1,1,1,1,1)

df
#>    A  B
#> 1  1  2
#> 2  1  3
#> 3  1  4
#> 4  1  5
#> 5  1  6
#> 6  1  7
#> 7  1  8
#> 8  1  9
#> 9  1 10
#> 10 1 11

总而言之，请确保您使用的是正确的对象。
