dt_separate doesnt work

[acpguedes]

Follow the code

library(tidyfast)

my_parser <- function(data, var ){
  dt_separate(data, col = var , into = c("key", "value"), sep = ":") #%>%
}

data.table::data.table(
  a1 = purrr::map2(letters[1:20], LETTERS[20:1], ~ paste(.x, .y, sep = ":"))
) -> myDT

myDT
#>      a1
#>  1: a:T
#>  2: b:S
#>  3: c:R
#>  4: d:Q
#>  5: e:P
#>  6: f:O
#>  7: g:N
#>  8: h:M
#>  9: i:L
#> 10: j:K
#> 11: k:J
#> 12: l:I
#> 13: m:H
#> 14: n:G
#> 15: o:F
#> 16: p:E
#> 17: q:D
#> 18: r:C
#> 19: s:B
#> 20: t:A

my_parser(myDT, a1)
#> Error in as.character(x): cannot coerce type 'closure' to vector of type 'character'

dt_separate(myDT, col = a1 , into = c("key", "value"), sep = ":")

Thanks. Will be updating the function in just a moment and will highlight how to use it within a function.
