Hello, I would like to use tidyfast for separate my data table faster so I installed it and tried to run the example you provided. However, the error was pop out and Im not sure how to solve this problem. my data.table is 1.13.0, is it because it is too old?

library(data.table)
library(tidyfast)
dt_separate(data.table(col = "A.B.C"), col, into = c("A", "B"))

Error in isFALSE(is.data.table(dt_)) : could not find function "isFALSE"

What could be the problem and any tips to resolve this? Thank you so much!

ok I found out it's data.table problem. my data.table is 0.1.13 but it required 0.1.14 for tidyfast!

Oh, that is good to know. I believe the isFALSE() function is available in a newer R version but I believe data.table offers it internally as well.
