Converting data defined as a factor to a date value

[marbpma]

Hello,

I'm relatively new to R Studio and I have not worked with time series often so this is probably a simple question. I am struggling to convert values such as the one below into a date value. Currently it is a factor.

4-Aug-89

I've tried as.Date() but it did not work for me and a couple lubridate functions.
Any suggestions?

Thank you in advance!

lubridate::dmy('4-Aug-89')
#> [1] "1989-08-04"

library(tidyverse)

df <- tibble(date = factor(c("4-Aug-89", "3-Aug-89", "2-Aug-89")),
             record = 1:3)

df %>% mutate(date = lubridate::dmy(date))
#> # A tibble: 3 x 2
#>   date       record
#>   <date>      <int>
#> 1 1989-08-04      1
#> 2 1989-08-03      2
#> 3 1989-08-02      3
