将 integer 列转换为最新

Question

I have a column in format 19990101 that I would like to change to date format. It is currently as integer.

I've tried the following but it results in

Error: unexpected symbol in: mutate(Date = Date, Date = as.integer(format)date.

mutate(Date = Date,
       Date = as.integer(format)date, "%Y%m%d")

Answer 1

mutate(Date = Date,
       Date = as.Date(format(x), "%Y%m%d")

The above code solved my issue.
