Tidyr单独返回错误"_tidyr_simplifyPieces“

Question

使用Tidyr分离将一列拆分为两列，返回以下错误：

df <- data.frame(ID=11:13, FOO=c('a|b', 'b|c', 'x|y'))

tidyr::separate(data = df, col = FOO, into = c("left", "right"), sep = 
"\\|")

simplifyPieces中的错误(片段，n，填充==“左”)：找不到对象'_tidyr_simplifyPieces‘

对于为什么会发生这种情况，有什么建议吗？

我分离了plyr并重新运行了代码，它现在起作用了。在dplyr之后加载plyr是一个很常见的问题。
