dplyr rename - 错误:`new_name` = old_name必须是符号或字符串,而不是公式

Question

我正在尝试重命名列,dplyr::rename()R正在返回此错误,我无法在网上找到任何地方.

Error: `new_name` = old_name must be a symbol or a string, not formula

具有2列数据框的可重现示例:

library(dplyr)
df <- data.frame(old_name = seq(1:10), x = seq(1:10))
df %>% dplyr::rename(new_name = old_name)

我希望这个新的简单数据框能够将第一列重命名为new_name.这也不起作用rename_().

当前R版本为3.4.3,dplyr版本为0.7.4.我无法在R版本3.3.3上复制它,但能够在R版本3.4.0上复制它.这是在一个完全干净的R会话上测试的.

我目前的解决方案是重写部分代码plyr::rename仍然有效,但这并不理想,因为它要求我重写大量代码.
工作示例plyr():

library(plyr)
df <- data.frame(old_name = seq(1:10), x = seq(1:10))
df %>% plyr::rename(replace = c('old_name' = 'new_name'))

Answer 1

正如@aosmith评论的那样,这是使用rlang软件包(来自GitHub)的dev版本和dplyr(来自CRAN)的发布版本的结果.完整的讨论在这里:https://github.com/tidyverse/dplyr/issues/3252

两个软件包都应该来自CRAN,或者来自GitHub; 不匹配是问题所在.要解决此问题,您可以将dplyr更新为dev版本,devtools::install_github("tidyverse/dplyr")或者将rlang安装恢复为当前的CRAN版本.

Answer 2

我有同样的问题。以防万一，更新所有软件包后，它就可以工作了（见sessionInfo()下文。

使固定

切换rename到select（由于某种原因正在工作）

df <- data.frame(old_name = seq(1:10), x = seq(1:10))
## df %>% dplyr::rename(new_name = old_name) # error
df %>% dplyr::select(new_name = old_name, everything())

plyr如果更新不能解决问题，这可能比策略更容易。
