Thanks for your informative video. 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. any guide on the syntax to use pls?
nice explanation! 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..
Hi Ben, i have monthly ts data that has 216 observations with decimals. I removed those decimals. Then when I bring it in r and try to plot it its coming different and clumsy. Further wehen I add another data series "year" in to the data file, the figure is coming as dot. So the trend is clear but the seasonal cycle of the figure is not coming, the way you have done in your slides. In the decomposition I found error: Error in decompose(d) : time series has no or less than 2 periods Would you please suggest me what is the problem in my analysis, Do I need to install any package? Here are my r codes: d
Hello, I really liked your tutorial thank you. However I have a question for you For a time series from 2020-03-02 to 2020-06-02 can we take frequency = 30 (30 days) in the ts () function like: timeSeries = ts (data, start = c (2020.03), frequency = 30). Thank you.
Setting this to 30 should work, but it depends on the data that you're working with. From the help page: "The value of argument frequency is used when the series is sampled an integral number of times in each unit time interval. For example, one could use a value of 7 for frequency when the data are sampled daily, and the natural time period is a week, or 12 when the data are sampled monthly and the natural time period is a year. Values of 4 and 12 are assumed in (e.g.) print methods to imply a quarterly and monthly series respectively."
I believe I used Zoom. You can share your screen and recored. I also used Zoom on my most recent video.. You can see me use zoom here th-cam.com/video/FEEz2zyaLUw/w-d-xo.html
How would you do a time series for an hourly time series?
Great! Can we have the complete script, want to see days time series

I have a column with date time for every minute for 2 years. I need frequency of this column to plot time series. How can I do that in R?
Hello! Is there a playlist with the other videos available somewhere? Or how do I know the proper order of the videos? Thank you!
Let me put this together
So clear!!! Thank you!!!
You're so welcome! I am glad you enjoyed the video.
what are basic temporal statistical summaries in time series?
nice explanation!
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..
It is really simpler than Python! That's i am sure!
It is, it almost feels like referencing excel functions
NICE INTRODUCTION
Hi, do you know of or have any tutorials using time-series cross-sectional data in R?
how can i use wavelets coherence on daily and yearly time series data
Hello, May I ask what is version of R are you using? thanks
I made this video a long time ago haha. I don't recall. I am sorry!

@@polarizedsquirrel3867 what if the times are only weekdays, say analysis of stock market, what is the frequency then?
@@shihuali341 I can not answer that but I know why you ask. Stock market is random walk. Can not be forecasted.
Which app do you record with?
