R-code: findintervals and calculate mean-values

[Ikhanda]

Hi everyone,

im currently starting to work with rstudio for analyzing data in university and i have an issue i can't fix on my own.
I have several files with thousands of data lines (raw data). What I wanted to do is to determine intervals under several conditions and then to calculate mean-values for these intervals automatically in two different ways:

(1) Finding several intervals which last for exactly 10 seconds when (simultaneously) two more parameters are zero and then to calculate mean-values for these intervals.
(2) I can determine the exact times. I want R to identify intervals that i determine and to calculate mean-values for these intervals.

I hope I was able to describe what I want to do and that the community can help me.

Thanks a lot
Ikhanda

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
