QUESTION
I am trying to create a way to track opening and closing of the breathing organ (i.e. a mouth) of several animals at the same time over the course of 45 minutes. The goal is to be able to calculate the total open time and frequency of opening for each animal. Basically, the idea is to have several stopwatches operating in parallel, while tracking two lists of values per animal: open time and close time.
The experiment would ideally go like this: I start the experiment and therefore the stopwatch. Every time animal 1 opens its breathing organ, I press open, and once it closes its breathing organ, I press close. The time of each, relative to the stopwatch started at the beginning of the experiment, are recorded in a dataframe for animal 1. This process repeats 10-15 times throughout 45 minutes. At the same time, another animal is opening and closing its breathing organ, and a separate dataframe for animal 2 is created using a different set of buttons. I would like to have this be possible for up to 10 animals simultaneously.
I have been able to make the stopwatches (example code below) using a watch
function, as well as include action buttons that output text corresponding to the difference in system time between start time of the experiment and time of pressing the open or close buttons. However, I am unsure of how to store these values in a dataframe for each animal.
I have looked around stackoverflow and found nothing that works, including this thread: r Shiny action button and data table output and this one: Add values to a reactive table in shiny
Let me know if you need any more info! Thanks in advance.

Answered 2020-Feb-20 at 01:15I think there may be a number of ways you could set this up differently.
One recommendation I have is to avoid putting output
inside of your observers
.
Another is calling your stopwatch functions only once - for data integrity, to make sure your display and data collected are the same.
In addition, it might be helpful to have a single data table store all of your open and close events, with an additional column for animal number. It would be relatively easy to work with a table like this for future analyses.
Here is a quick example you can try out, just to get a sense of the behavior. Please also add tableOutput('table')
to your ui
after your conditionalPanel
to view the data frame.

How to call a user defined method in angular material table? I am using a class object instead of an Interface and when I call that method and its not working. I was able to display the properties but not the method output.

QUESTION
Error on server console: UnhandledPromiseRejectionWarning: RangeError: Maximum call stack size exceeded
Meteor 1.8.1
Project worked fine at 1.6.x, MongoDB 3.2.x
mlab pushed me to mongo 3.6.x and now some of my charts (chart.js) and tables (aslagle:reactive-table) aren’t working.
Both of these are generated via aggregate/pipeline (example below).
Long story short, I’ve neglected this project for several months and just getting back to it, ran into this issue, and tried updating to 1.8.1. Which has me at mongo 4.0.6
Charts and tables still not working and I think it’s because I’m missing some update to the syntax/structure in the aggregates and/or pipelines. I could very well be wrong here as I’m rusty, not a dev by trade and as mentioned haven’t touched this in a few months.
Here’s one failing aggregate/pipeline that’s used to draw a line chart (Chart.js):

Answered 2018-Nov-06 at 09:24You can use a ReactiveVar or ReatciveDict to display data reactively. You need to make it iterable, first. Best is to do this in the Template.onCreated function. Lets say your Template has the name "myTable":

QUESTION
I couldn't find any question or answer about using a onchange event on Reactive Table.
I can console.log click events whenever I press any row on the table and log the values on that row. But I'm having trouble logging whenever one of those field values changes. Probably I have an error in my syntax, I just can't figure it out and how to get it to work.
Here's my code:

elements cannot trigger change
events. You are looking for data changes not user interaction so a better way to handle this is to use observers:
QUESTION
This is a follow-up to a previous question here: Add values to a reactive table in Shiny
Perhaps this is a rookie problem, but worth a shot. It's my first Shiny app.
I'm making a Shiny app that will allow users to store their inputs and values calculated from their inputs to a data.frame. This will be so they can compare values in the output. I've made a mock up of my code where I want to store 3 columns: inputs A and B, and a function based on inputs A and B.
I think my failure to understand evaluating reactives is my shortcoming here, so I'm turning to the community for help. I can get the code to work if I am just storing inputs and not the reactive function 'calcAB()'. Once I include the function, everything breaks down. I get an error:
