In this video, I walk through how to handle datetimes in R using the "lubridate" package. In this tutorial we will do the following things:
1) Creating date & datetime objects
2) Isolating components of the datetime
3) Time spans (durations, periods, intervals)
Please note that some of the code in this tutorial was adapted from Chapter 16 of the book "R for Data Science" by Hadley Wickham and Garrett Grolemund. The full book can be found at: r4ds.had.co.nz/#

A good cheat sheet for lubridate functions can be found at: rstudio.com/re...
A vignette for lubridate can be found here: cran.r-project...
And the following is a good reference: lubridate.tidy...

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

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

@RichardOnData 3 года назад

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

@neelkamalCHOURASIA 3 года назад

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.

@RichardOnData 3 года назад

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))

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!
