kandi X-RAY | mplot Summary
The mplot package provides a collection of functions designed for exploratory model selection. We implement model stability and variable importance plots (Mueller and Welsh (2010); Murray, Heritier and Mueller (2013)) as well as the adaptive fence (Jiang et al. (2008); Jiang et al. (2009)) for linear and generalised linear models. We address many practical implementation issues with sensible defaults and interactive graphics to highlight model selection stability. The speed of implementation comes from the leaps package and multicore support for bootstrapping. The mplot currently only supports linear and generalised linear models, however work is progressing to incorporate survival models and mixed models.

QUESTION
I'm using pine editor for coding in TradingView, I 'm using 3 supertrends, now for a downtrend, 1st supertrend gives Sell[Red in color] signal and starts with red line downwards, after that 2nd supertrend gives Sell [Orande in color] signal and starts with red line downwards, similar process for 3rd supertrend[purple color], over here if all the supertrends are giving Sell signal, then I need to show one big parent SELL sign indicating that all the SELL conditions are satisfied, now if one of the signal turns green indicating Buy signal and later on it turns red i.e. SEll signal, again a parent SELL sign should be visible on the chart. this gives a hint that I need to short from here. I have attached screenshot could you please help me with the code.
Here is the code for your reference

QUESTION
I am working on a little widget with holoviews and panel - it consists of reading a pandas.dataFrame and display a curve for each column. The interaction I need is to be able to add/remove columns from the plot.
In my real use case, there are too many columns so I can’t take advantage of the interactive legend already provided by bokeh+holoviews.
I made a little example that ‘’’ kind of works ‘’’ but I am probably doing it wrong, as I am reloading the data for the plot every time there is an interaction with the panel.widgets.MultiChoice (which is obviously wrong)
ANSWER
Answered 2021-Mar-03 at 11:24I think you just need to do your data loading first and not overwrite the dataframe, like:

I am developing a shiny app application and use a mainPanel() with tab panels. The first tabPanel() is supposed to contain a tableOutput() together with a downloadButton(). The downloadButton() is aligned like the image below.
Only when the output table is produced it goes down. I want it to be aligned at the bottom of the table from the beginning. What should I change in my code?

QUESTION
I'm looking at this answer from another question and trying to test it out.
One problem I'm having is a couple of the methods seem to have changed in newer versions of Androidplot. For whatever reason I can't figure out what replacement methods I'm meant to use.
The methods in question are:
- mPlot.getSeriesSet().iterator().next() //Cannot resolve getSeriesSet
- ValPixConverter.valToPix //Cannot resolve ValPixConverter
- widget.getXVal //Cannot resolve .getXVal
My ultimate goal is to be able to place markers on the graph traces
EDIT:
Ok I've figured getXVal/getYVal gets replaced with screenToSeriesX/screenToSeriesY, the rest are still unknown :(
...ANSWER
Answered 2020-Jan-16 at 23:58I eventually figured it out :)
mPlot.getSeriesSet().iterator().next() gets replaced with plot2.getRegistry().getSeriesList().iterator().next()
getXVal & getYVal gets replaced with screenToSeriesX & screenToSeriesY
For ValPixConverter I just copied the class from an older version of Androidplot.
This was enough to get me playing around with placing markers/cursor on the graph but a better solution will be formulated for the future.

QUESTION
I am quite new to the Android Development and I really need your help. My problem is in the MainActivity below. The app essentially displays a list of movies in the main activity and the movie details in another activity. And the problem is that whenever a user comes back from the MovieActivity to the MainActivity, the loader starts loading data again, although the movies are already there. And then it can not stop loading the data. It is really annoying. I want to get rid of this. So when a user comes back to the MainActivity, the loader will know that there is already loaded data and will not load anything again.If it helps, here is my full GitHub repo https://github.com/mateuszwojnarowicz/PopularMovies
I am stuck for about 3 weeks and have tried hundreds of possible solutions. Nothing seems to work. I feel really desperate.
Thank you so much for help,
Matthew
...ANSWER
Answered 2018-Aug-06 at 14:13Because you are new to Android there is a lot wrong. So, many people probably won't want to chime in. Regardless, I'm new as well and in the same class as you are right now, so I'll give it a shot.
First, your loader is not returning the correct data type. Your loader should be of Loader> and it should return a new AsyncTaskLoader>. The reason you want this is to make use of everything the AsyncTaskLoader has to offer. I'll explain further.
Second, we'll cache the data inside the loader by moving the initial reference from the Activity into the loader.
So move private ArrayList mMoviesCollection; as an instance variable of your AsyncTaskLoader. Remove the line mMoviesCollection = new ArrayList(); from both your onCreate and initialize methods.
In your AsyncTaskLoader, you need to check if your data exists already in your onStartLoading before forceLoad and implement deliverResult.
So, your onStartLoading() should look like this:

I'm working on a program that can calculate the slope using the linregress native scipyy function, but I'm getting two errors (depending on how I try to fix it). The two lists should be two-dimensional, basically x and y values.

You'll have to call linregress twice, and handle the five return values. For example,
