Any suggestion to what to do if the collumn name are the dates and the data is across...
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!!!!!!

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..
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?
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
Hi there!
I need to take out the maximum values from a diary data serie. I have to extract the maximum values from each year. How could i do It?
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.
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?
I have a variable "ACCIDENT_TIME" , it is in chr class..how should I convert it to the proper class
What if we want to convert date time to just date
Hi I want to convert date column in data file from DDMMYYYY to YYYYMMDD, how I can do?
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:

@@DataDaft Thank you!
shall we deal with DDMMYYYY date format?
I would like to convert these dates with format YYYYMMDD to a Date class.
dates
I'm no expert in R, but I think you should have it as "%d-%m-%Y".
