在 R 中将日期对象从“%Y/%m/%d”更改为“%d/%m/%Y”

Question

如何将 date object 的格式从 "%Y/%m/%d" 更改为 "%d/%m/%Y"。我试过 below-mentioned code 没有太大成功。

as.Date(bank$date,format="%d/%m/%Y")
      [1] "2007-11-02" "2007-11-09" "2007-11-16" "2007-11-23" "2007-11-30" "2007-12-07"
      [7] "2007-12-14" "2007-12-20" "2007-12-28" "2008-01-04" "2008-01-11" "2008-01-18"
     [13] "2008-01-25" "2008-02-01" "2008-02-08" "2008-02-15" "2008-02-22" "2008-02-29"

感谢您的帮助。

date <- as.Date("2007-11-02")
new_date <- format(date, "%d/%m/%Y")
new_date
#> [1] "02/11/2007"
