R dplyr 过滤列名中的空格/特殊字符

Question

require(dplyr)
sampleDF <- data.frame("Column A" = c(1,2,3))
sampleDF %>%
  dplyr::filter(
    `Column A` > 2
  )

How should I fix the codes above so it works? I don't want to change the name.

dplyr is probably not the problem, because in general only dots and underscores are allowed in variable names, but no spaces. If you would like to include a quoted name under all circumstances, maybe:

require(dplyr)
require(rlang)
sampleDF <- data.frame("Column A" = c(1,2,3))
sampleDF %>%
  dplyr::filter(
    eval_tidy(quo("Column A")) > 2 # OR: eval(quote("Column A")) > 2
  )
