Thank you, Richard! Great tutorial! Is there a direct way to convert dates to categorical variables? E.g. dates > 2020-01-01 to be 1 and

Thanks for your informative video. I am new in r and self-learning. Please I want to plot a time series graph in r. I want my x-axis have a the date as it is, ie 01-02-023 which stands for day, month and year with two weeks intervals. any guide on the syntax to use pls?

Thanks 😊

It doesn't seem the lubridate function "hm" handles 24 hour format characters. I.e., "2045" --> hm("2045") Any thoughts on converting integers into 24-hour time formats? The data in the dataframe are all integers which can be converted in characters easily, but converting from "2045" --> 20:45 is more tricky. Best regards!

Sir, Thanks it's a great explanation, I want to calculate mean of observation data with respect to minute, hourly, and 24hrly, monthly, separately. May u suggest or help me.

You can create these variables with lubridate functions minute(), hour(), etc., and so using the dplyr functionality assuming a data frame called "df", a timestamp called "time", and a variable called "var": df %>% mutate(minute = minute(time) %>% group_by(minute) %>% summarize(minuteMean = mean(var))

Thanks for this videos, I have a query, How to fill gap of datetime step ? I have a time series of 1 year "2010-01-01 00:00:00" like that, In which there are some time step are missing , How to filled the gap or irregularities . Thanks

Could you clarify the question? Do you mean how you add hours, minutes, or seconds to something like the 00:00:00 component? If so you could use the dhours(), dminutes(), or dseconds() functions. For example something like "2010-01-01 00:00:00 + dminutes(5)" would yield "2010-01-01 00:05:00".

Thank you

Wait, so does ymd_hms() essentially do the same thing as as_datetime()?

please help me with this i need to categories time into early morning, morning, mid-day, afternoon, evening..please tell me the line of code for it..

That's fine. But you did not explain if I need to convert an entire column formally formatted as character and I also need to find the diftime I would appreciate if you can explain this

Nice

How do I calculate number of days between two dates?

You can use the "difftime()" function from base R. Or alternatively create an interval object, and then use as.period(..., unit = "day").

you explain bad bro. Only half explainations
