Re: [R] periodicity

Ummm... ??? A google search on "R function periodicity" immediately brought up the xts package and others. and RStudio is **NOT** R. It's an IDE for R (and there are others). Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus

Hi Nick, A quick look on rseek.org didn't turn anything up. It would help to know what websites you're referring to - they might be loading custom code. Sarah On Wed, Jan 30, 2019 at 2:17 PM Nick Wray via R-help wrote: > > I've found references on websites to an R function "periodicity", but th

[R] periodicity

I've found references on websites to an R function "periodicity", but there's no such built-in function as far as I can see in R studio. I can't find reference to it being part of any package either. Can anyone help with this? Thanks, Nick Wray [[alternative HTML version deleted]] ___

[R] Periodicity of Weekly Zoo

Hi List, I have weekly sales observations for several products drawn via ODBC. Source data is available at https://www.dropbox.com/s/78vxae5ic8tnutf/asr.csv. This is retail sales data, so will contain seasonality and trend information. I expect to see 52 or 53 observations per year, each observat

Re: [R] periodicity validation

alright this is what you want to do. install.packages("fields", dependencies=TRUE) tim.colors is in this package and it has a blue to red color scheme- blue being the lowest and red being the highest. This color scheme makes sense to me and is a common thing that a people (read engineers) familar

Re: [R] periodicity validation

all of the functions that I listed are time series tools for looking at what I think you want. this can be done you just have to understand the methodology. So, look at some of the things that I suggested, If these don't help then I don't understand what you want, and it is necissary for you to

Re: [R] periodicity validation

The data I mentioned above is oscilating vs time，but there are not obersevable fixed cycle if I just plot this data. How to get the average cycle，or the most probable range of cycle with statistical methods? I don't know how to achieve it by R, is there any command? On Sep 11, 10:52 am, "stephen

[R] periodicity validation

There is a series of data contains time in fixed step and energy varying with time, how to test its periodicity?In R, it seems there is no direct tools since I have search the R manual with periodic and I have not found any related topic. Thanks a lot __
