dplyr:：当列名包含空格时，mutate_if失败

我有以下情况：我有一个tibble和一个字符向量，它包含了一些所说的tibbles列名。现在我使用dplyr:：mutate_if将这些列设置为0，其名称包含在字符向量中。为此，我提供了一个逻辑向量作为谓词

到目前为止，这已经奏效：

library(tidyverse)

test_OK <-
  tribble(~"Var1", ~"Var2", ~"Var3",
          11,      12,      13,
          21,      22,      23,
          31,      32,      33)

vars_to_change_OK <- c("Var1", "Var3")

## Everything works out
test_OK %>% mutate_if(names(.) %in% vars_to_change_OK, funs(. * 0))

然而，我感兴趣的是为什么上面的内容在dplyr中不起作用

更新：我添加了sessionInfo，以防版本很重要：

我们可以使用mutate_at并将“vars_to_change_FAIL”放在vars中

谢谢你的解决方案！然而，我对我的代码失败的原因感兴趣/如果我不正确地使用mutate_if。@AEF您有哪个版本的dplyr？@AEF请将您的dplyr更新为0.7.0，它应该可以工作。我已将我的会话信息添加到问题中。这是dplyr 0.5.0。有什么特别的原因不使用mutate_吗？请注意，错误仍然存在remain@GGamba不，我当然可以换一种解决方案。然而，我不知道为什么它不起作用，甚至不知道它是否应该起作用。
