Original dates have been given in POSIXct format. I need to convert it to dd-mm-yyyy. Thanks.

I think gsub solves your problem.

df$date is your column in which date is inside.

df$date <- gsub("/", "-", as.character(df$date))

Assuming your input dates are in dd/mm/yy format:

as.POSIXct('02/11/18', format = '%d/%m/%y') |> format('%d-%m-%Y')
