convert column of date to char in R, keeping same format

I have:

library(tidyverse)
library(lubridate)
data <- tibble(date = ymd("20220224"),
       number = 1234,
       decimal = 12.34,
       char = "20220224")
)

I want to convert the date column to character, and keep the exact format, ie 2022-02-24

performing as.character(ymd("20220224")) works perfectly, and I get "2022-02-24"

but, when I apply this to the column, data[,"date"] = as.character(data[,"date"]), I get the char of the date counting days since Jan 1, 1970.

How can I get it so that I get the characters as desired? I want to see "2022-02-24", not "19047"

thanks

>Solution :

tibble will return a tibble after you have subsetted it using [. Therefore you need to use [[.

library(tidyverse)
library(lubridate)

data[,"date"] = as.character(data[["date"]])

# A tibble: 1 x 4
  date       number decimal char    
  <chr>       <dbl>   <dbl> <chr>   
1 2022-02-24   1234    12.3 20220224
