Your video sounds good, but my date variable format is a “chr” with values like “35357” after importing from Access. How can these variables be converted to a date format? Thanks!
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! I have one question, if I have two columns, date1 and date2, and I want to find the minimum date between the 2 columns, is there a specific function?
great explaination! i have a dataset containing time period, I want to categorise it into early morning, morning, mid-day, afternoon, evening... kindly suggest me a line of code for it..
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/
Thanks very much for making such wonderful videos. I learned many packages from watching your videos. I have a small query, can you please explain how to extract a month from the year-week format date? Ex: "2018-3" (%Y-%W) to Month. I tried searching the net unable to find the answer.

Hello, thanks so much for this lesson. Would you be able to explain how to cane the times zones? For example from UTC to EST
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:

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