Ron,
I hope this will be helpful.
require(lubridate, quietly = TRUE)
require(stringr, quietly = TRUE)
test_date_str1 <- "6/3/2012"
test_date_1 <- mdy(test_date_str1, quiet = TRUE)
test_date_1
test_date_str2 <- "2-3-2011"
my_date_strings <- c(test_date_str1, test_date_str2)
my_dates <- mdy(my_date_strings, quiet = TRUE)
make_date <- function(.date, sep = "/") {
str_c(month(.date), sep, day(.date), sep, year(.date))
}
make_date(test_date_1)
make_date(my_dates)
A slightly more complex function allows you to take more advantage of the
lubridate package.
require(lubridate, quietly = TRUE)
require(stringr, quietly = TRUE)
test_date_str1 <- "6/3/2012"
test_date_1 <- mdy(test_date_str1, quiet = TRUE)
test_date_1
test_date_str2 <- "2-3-2011"
my_date_strings <- c(test_date_str1, test_date_str2)
my_dates <- mdy(my_date_strings, quiet = TRUE)
make_date <- function(.date, sep = "/", label = FALSE, abbr = TRUE) {
str_c(month(.date, label, abbr), sep, day(.date), sep, year(.date))
}
make_date(test_date_1)
make_date(my_dates)
make_date(my_dates, sep = "-", label = TRUE)
make_date(my_dates, sep = " ", label = TRUE, abbr = FALSE)

Thanks Jim for your reply.

forgot you were asking for mdy format

format(asd, format = '%d/%m/%Y')
