POSIXct back to character, specific format

Question

lets say we have a character vector of like:

vec <- "1/1/2000"

at some pont we turn this into a date via

newvec <- as.POSIXct("1/1/2000", format = "%d/%m/%Y")

Now let say we want to make it a character again we can do:

as.character(newvec)
[1] "2000-01-01"

the new format is Y-m-d. How can we turn newvec into "1/1/2000" ?

Answer 1

Like this:

as.character(newvec,'%d/%m/%Y')
# [1] "01/01/2000"
