NitroGen

UPDATE: I've found a mistake - I used plotOutput instead of plotlyOutput. All is fine now.

I want to build a Shiny dashboard that does something like that:

• takes a dataset with a numeric variable value
• uses Numeric Input widget to obtain a numeric value
• creates new variable value2=value*number provided in the Numeric Input box
• plots a bar chart

The sample code is below. It correctly places the Numeric Input box, but the chart does not appear (the box where the chart is supposed to be is completely empty). Why?

Going nuts. I have a melted dataframe that I am trying to display in a simple grouped barplot in ggplot2:

Hi everyone I am new to angular. I am trying to create mat-cards for each object in an array however no cards appear.

I'm trying to fit a Quadratic-plateau model to agricultural data. In particular, it's Nitrogen fertilization and corn yield response to it. It's a common practice in research.

It's very common to do it using R, like in this following example- https://gradcylinder.org/quad-plateau/

but it lacks examples and resources when it comes to python. I've managed to find a great library, called eonr (https://eonr.readthedocs.io/en/latest/) that does what I'm looking for (and much more) but i need more flexibility and more options for visualization.

Through the eonr gallery I found the function it uses and the parameters for the fitting done by scipy.curve_fit.

I want to output some sentences when the user presses the wrong button and then exit using tkinter module (like says "idiot" or something) when they answer a question wrong and exit the process. However, command=lambda: only support only one action and the python interpreter will output an error when I add multiple lines. Is there any way to perform two or more actions for the windows made by tkinter?
This is part of the codes and I want the codes to output the self.correspondingBehavior part and then exit.

I'm trying to make a quiz with JavaScript and html. The user is asked to enter an answer of a question in a prompt field, the users answer and the right answer is sent to a function that compares them. If the answer subtracted with the right answer equals zero, the function will return a Point. If that isn't true the function won't return a point. If the answer from the user is anything other than 1-3 the function alerts of an invalid input. Everything here works however I want to add a feature that makes the code ask the same question again if the users answer is invalid, in other Words not 1-3. I've tried using while loops but can't get that to work. Any suggestions to how I could solve this and/or any other tips to make the code more structured.

I am processing netCDF data for multiple years. The netCDF is for air pollutant data, and the latitude and longitude are provided as separate variables, not as part of the original grid.

LINK TO DATE: Sample Netcdf

These netCDF files provide Level 2 Nitrogen Dioxide data and they are downloaded from NASA Earthdata portal. The satellite is Sentinel-5P and the instrument is TROPOMI.

So when processing this data, you have to create variables for NO2, latitude and longitude. I am trying to create raster layers, and then save them as GeoTIFF files for my research.

The problem here is related to the fact that I don't know how best to create these rasters. The latitude and longitude is not equally spaced throughout the dataset, and I haven't figured out a way to accurately create these images. I created a model grid using the number of rows and columns provided by the netCDF files. In the list of variables this is called the scanline and ground_pixel, but when I plot it the cells in the final image don't look right.

This is how I upload the data:

I'm still quite a beginner and my friend (who's not answering so far) provided me a code for downloading a genomic sequence from Ensembl.org and writing it to a *.csv file using dictionaries. Unluckily, the file contains only one column and 89870 rows, I'm not sure how to fix it. It would ease my work with counting because it acts weird when doing plots. I don't know where could be a mistake. Here's the code:
