stationary | Stationary distributions for arbitrary finite state Markov

I'm making a top-down shooter game in java where I have a stationary player who can turn side to side and can shoot a gun at enemies that move to the center(where the player is). I have made different faces for each side when my player turns, but I'm not able to figure out how to switch the faces when I use the arrow keys. Here is my main panel:

Okay so what I really want to do is to style a charfield which has choices from my forms.py modelform class.

My models.py has this code it it...

I'm using a component to render a dynamic table which has "many" rows. Sometimes I add new rows, sometimes I modify existing rows, but whenever I do any of that, Vue will re-render the entire table and that takes a considerable time, which I would like to avoid.

I'm using keys and stuff to accelerate the re-rendering process, but I still feel the process is inefficient: Vue will at least run through each row, checking whether it has changed or not.

I am new to Shiny and it really gives me headaches this problem. I have made a Shiny app where you upload an excel, set some variables and then makes some statistical test on that variables( first a regression model then model assumption). I need to export a pdf file which contains the outputs of the regression model and the statistical test along with the conclusions of the tests.

I am using knit2pdf and this is my code: Server:

I'm doing a project on data analysis with timeseries and forecasting. I have a dataframe which contains a lot of data from which I need to handle Covid cases. The dataframe looks like that:

I have a simple bevy test app, that displays an array of cubes and an FPS counter in the upper left corner. The 3d scene can be zoomed and rotated.

I recently tried to upgrade the following code to bevy = 0.5.0.

Old code block (bevy = 0.4.0):

I'm newbie in Shiny, trying to make an app where I would like to make an overall statistical analysis (on time series) based on a dataset which I prior loaded. The problem is that I do not know how to "work" with a specific variable from dataset. I would like that the variable to be taken "dynamically", something like, datos[,2], but I do not know how to do this. Now I use attach function and then set y manually. So my code for now is:

I'm using Vue.js version 3. Here is my full code with dummy data and options API with filters and sorting, and everyting works very well
