Thanks a lot!

Thank you for that video! However, I'm still stuck... I'd like to convert a column extracted from Excel that is in numerical time (0.54036, 0.55625) to a proper date-time format (13:02, 13:21...). I use data from public transit data sources, in such way that 1.00833 is 00:12. Would you have the code to do that?

Thank you, very helpful Posixlt in 5:29

I'm no expert in R, but I think you should have it as "%d-%m-%Y".

What do we do if the data is not formatted in one of those ways? For example, my data is in the format: 1/1/2021. Thank you!

You have to use the appropriate date format codes to match your format. For a date in numeric month/numeric day/four digit year format you would use: as.Date("1/1/2021", format="%m/%d/%Y") (Basically the same as the first one shown, but using %Y instead of %y) Some common codes: # %d - Day # %m - Numeric Month # %b - Abbreviated Month # %B - Full Month # %y - 2-digit year # %Y - 4-digit year This blog post has a list of format more codes: www.r-bloggers.com/2013/08/date-formats-in-r/
