pivot_longer 来自 tidyr 文档的问题

Question

I've been following along with the Tidyr official documentation，因为我已经有一段时间没有使用它了，正在尝试更新它。

涉及 billboard 数据集的示例之一产生以下错误：

library(tidyr)

billboard %>% 
  pivot_longer(
    cols = starts_with("wk"), 
    names_to = "week", 
    names_prefix = "wk",
    names_transform = list(week = as.integer),
    values_to = "rank",
    values_drop_na = TRUE,
  )

Error in pivot_longer(., cols = starts_with("wk"), names_to = "week", : unused argument (names_transform = list(week = as.integer))

我对发生的事情有点困惑，因为正如我之前提到的，这在官方 tidyr 包文档中。

Answer 1

当前 CRAN 版本 tidyr -1.1.2 returns 输出没有任何错误

billboard %>% 
  pivot_longer(
     cols = starts_with("wk"), 
     names_to = "week", 
     names_prefix = "wk",
     names_transform = list(week = as.integer),
     values_to = "rank",
     values_drop_na = TRUE,
   )
