Dear, How to arrange the code to have the class of x_month also as a "Date"?

[richardyeung]

doesnt work Error in parse.format(format[1]) : unrecognized format %m, I have a list of dates, not a single date

I would like to convert these dates with format YYYYMMDD to a Date class.

dates <- data.frame(Date = c("22-02-2012", "20-11-2006", "14-05-2015", "18-12-2016"))

I tried:

dates <- as.Date(dates, "%Y%m%d")

And I get the following error:

Error in as.Date.default(dates, "%Y%m%d") : do not know how to convert..
Please give solution please..
