Predator | A screensaver for macOS which is based on the predator

i'm confused with the following condition, simply i want to have arrayformula or maybe a custom-formula to increment number in a way bound by specific condition based on value in other column, put it simply :

if the group doesn't change and sub-group is different increment number by 1
else if the group doesn't change and sub-group is doesn't change (same) hold value by previous
else if the group change regardless sub-group value reset number back to 1

for ilustration

** notes Number is the result that i want, in example i fill it manually

Given below is the code for importing a pipe delimited csv file to monogdb.

I have a ~4GB txt file which is pipe delimited. I am trying to import this text to MongoDB but as you know MongoDB supports only JSON and CSV files. Below is the code so far.

I have the following data frame regarding a predator, prey interaction, SS=surf.smelt, SL = sandlance and H = herring.

Essentially all I need is another column that states whether there was more than one species available for the predator during the interaction. For example, If you look at index 12, the Prey was SL, but there was 1000 sandlance and 100 herring available, I need a column that can simply show with a 1 or 0 if there were more than 2 species available for the predator.

If possible, I would also like to show what other species was available in long format

Date frame I have:

I am working with fish telemetry data in R, with a simplified dataset provided below:

I want to validate the input of the textfield by pressing a button. When a user puts in a specific word in the textfield (for example: Predator) it should trigger the TextfieldVal Boolean and set it to true when the button "Send" is pressed. Anything else put in the textfield other then predator should be false.

Now I've been searching the internet for hours and still couldn't find my answer. Asked some people in my environment, but they can't help me either. Could you please send me in the right direction.

This is the code I came up with so far. The bool works, but I miss the function of making it work as intended. So validating the textfield and making a specific word return a true, anything else a false.

I want get my data from an API. The API itself works fine in postmap like this :

I am working with Netlogo to create a realistic predator prey-model and am stumped at the distance command.

How do you wrap text around an image in HTML and CSS? I have an image and a text next to it, but it would not go below the image. how could I make text go around the image? What would be the best way for the text and image to looks when we view on a phone screen.

I cannot any useful way on the internet. I am quite new to html

Thank you.

here is my code bellow
