After updating R to 3.5.1, my code:
IEU %>% mutate_at(vars(c(IEU_Submission_Date:IEU_Disbursed_Date)), excel_numeric_to_date)
could no longer function, with the error:
Error in mutate_impl(.data, dots) : Evaluation error: missing value where TRUE/FALSE needed.
due to there being NA's present in 4 of the 5 columns. Previously, it was ignoring the NA values. Not sure if this is due to dplyr or the janitor
excel_numeric_to_date() function. I would not like to remove these rows with NA values, but rather keep them as NA.
Thank you kindly for your support.
