kandi X-RAY | plumber Summary
Plumber allows you to create a web API by merely decorating your existing R source code with roxygen2-like comments. Take a look at an example. These comments allow plumber to make your R functions available as API endpoints. You can use either #* as the prefix or #', but we recommend the former since #' will collide with roxygen2. You can visit this URL using a browser or a terminal to run your R function and get the results. For instance will show you a histogram, and will echo back the 'hello' message you provided. Here we're using curl via a Mac/Linux terminal. As you might have guessed, the request's query string parameters are forwarded to the R function as arguments (as character strings).

QUESTION
Similar questions on stack overflow but not quite what I need. So I have a parent div with multiple checkboxes wrapped in labels, I then attached a click event on the parent so it bubbles to every child element. My problem is the class is toggled fine when clicked on the label (it's a class that changes the style of the label), but when I click on the actual little checkbox it does not work since it adds the class to the input and not the label, how would I make it that the class is toggled on the label even if the event. target is on the checkbox input
...ANSWER
Answered 2022-Apr-11 at 15:06Although I think this might not be the best solution or best practice, it worked. What I did was attach another listener to the label

I'm new to shiny , couldn't get my answer anywhere tho. I have a heavy code aggregating tables in R. I wanted to move it to the Web app and I chose Shiny as my original code is written in R so I thought it saves me lots of time.

...ANSWER
Answered 2022-Mar-22 at 14:52After a long investigation, I think I found the answer. I'm writing it down here as you might face this issue quite often developing your web app by Shiny. Always there are some big processes you wanna do and wanna make sure your async works great. There are libraries (future & promises packages) that Cheng explains them here. it says, they can take the calculations in the background and make them come back with the result while the shiny app is doing its normal job. It didn't work for me and I still had my web app stalled. But what I saw, they did increase mybigcalculation speed dramatically. Also it took it to the background makes it invisible in the console.
I found my answer in a package called Shiny.worker library. Now my app is working fine while my expensive code is running in the background. I made my ideal execution(fast and async) by wrapping future package inside of a shiny worker library. So it looks something like this:

QUESTION
I'm unable to deploy a tidymodel with vetiver and get a prediction when the model includes a variable with role as ID in the recipe. See the following error in the image:
{ "error": "500 - Internal server error", "message": "Error: The following required columns are missing: 'Fake_ID'.\n" }
The code for the dummy example is below. Do I need to remove the ID-variable from both the model and recipe to make the Plumber API work?
...ANSWER
Answered 2022-Mar-11 at 14:46As of today, vetiver looks for the "mold" workflows::extract_mold(rf_fit) and only get the predictors out to create the ptype. But then when you predict from a workflow, it does require all the variables, including non-predictors. If you have trained a model with non-predictors, as of today you can make the API work by passing in a custom ptype:
QUESTION
I have a function/method written inside a class:
...ANSWER
Answered 2022-Mar-10 at 15:12Yes, because of the way eval works, essentially, since you are implicitly passing a different object for locals and globals (since it just gets globals() and locals()), the expression is being evaluated as if it were in a class definition, which does not create an enclosing scope. The behavior is described in the docs:
If the locals dictionary is omitted it defaults to the globals dictionary. If both dictionaries are omitted, the expression is executed with the globals and locals in the environment where
eval()is called.
and if to keep reading in the exec docs:
Remember that at the module level, globals and locals are the same dictionary. If exec gets two separate objects as globals and locals, the code will be executed as if it were embedded in a class definition.
And class scopes don't create enclosing scopes, which is why you can't call methods without using self.
Here is another way to reproduce:

QUESTION
I prefer to use my local laptop for cost reasons + having an IDE like Visual Studio Code. As it stands my IT department is also not able/reluctant to setup database connectivity for could 9 etc. (so I would have to move data into S3 from local laptop). I also investigated this to SSH into an EC2. However, again IT is unwilling to open up network connectivity ...
The issue I have is, that my laptop only has 8GB (windows). So from time to time I would like/have to use the cloud (e.g. to do hyperparameter optimisation etc.) and ultimately deploy models (e.g. as docker images R + plumber - Python + FASt API etc.). Coming across code like this (run in sagemaker notebooks):
...ANSWER
Answered 2022-Jan-17 at 10:03You can. Use SageMaker Local to execute training and inference locally in docker containers on your laptop.
In the Estimator, you'll specify: instance_type='local' or instance_type='local_gpu'
