QUESTION
I would like to update both a data.frame
and a DT::datatable
interactively when editing the datatable
cells. This works fine but when I use the selectInput
function to filter the data.frame
and edit cells in another row of the datatable
, it just copies the values I edited previously both in the data.frame
and datatable
. Any suggestions?
Below, is a reproducible example. I guess that this is an issue of reactivity. Being new to Shiny I am still far from mastering that.
...ANSWER
Answered 2022-Feb-20 at 18:29A few modifications to achieve expected behavior :
dtProxy
should be created only once at server launchobserveEvent(input$dt_cell_edit,...)
should be independent ofobserveEvent(input$s_internal_idNew,...)
df_showed()
should also be updated, asdf()

QUESTION
I am practicing react right now, doing a sorting visualization app. I am stuck with implementing the sorting function (the idea is to add some delay between iterations to make it possible to see changes in real-time).
There is in my code a class component that contains bubbleSort() method (that calls function* bSort) and render() method (that do changes when this.state.array changes on each function iteration).
It works this way: when I call bubbleSort() array of numbers (which affects rendering) changes only ones.
For example:
- Input: [5, 4, 1, 2, 3]
- Iteration 1: [4, 5, 1, 2, 3]
- Iteration 2: [4, 5, 1, 2, 3]
- Iteration 3: [4, 5, 1, 2, 3]
Here is a part from component class:
