我通过只提取id列中-PRD之前的数字替换了id列中的信息。
我正在尝试创建一个新的id列,以使用这些数字替换以前的列。我尝试过以下操作:

library(stringr)

str_sub(word(unique(df$id), 1, sep = '-'), -2, -1)

但我收到了这样的信息

Error in `dplyr::mutate()`:
! Problem while computing `new_id = str_sub(word(unique(df_sum$id), 1, sep = "-"), -2, -1)`.
✖ `new_id` must be size 7 or 1, not 58.
ℹ The error occurred in group 1: id = "AC12-PRD-C1".
Run `rlang::last_error()` to see where the error occurred.

有谁能帮忙吗?

df$newid <- str_extract(df$id,"\\d+")

这应该可以。如果你需要它作为数字而不是字符串,就用as numeric Package 它...

使用sub的方法

df %>% 
  mutate(id = sub("-.*", "", id))
# A tibble: 202 × 6
