I have an Array of Object that is declared and look like this:

In Autohotkey, I have the following code :

I am a novice R user hoping for some help:

I want to write some code where I can input a vector and determine how many times each item fell within a category. For example, if I had three categories in a data frame and a vector in question:

Given the below dataframe:

I've got array like this with few values : name, number ( int or float) and %. This is how it looks :

I'm new to Javascript and I'm trying to learn express and create an application that will allow users to create new recipes, browse existing recipes, and view recipes.

I've got my server running by typing recipeserver.js in the cmd bar and then typing localhost:3000 in my address bar on google chrome. So far it loads the index.html homepage and from there, I am able to click on a link titled "Create a Recipe" which leads me to the create.html page that looks like this:

create.html page

Initially, there will be only three recipes on the server, which are included in the database object within the recipeserver.js code I've included below. The create.html page allows a user to enter recipe information. When the Save Recipe button is clicked, the addrecipe.js file is supposed to send the recipe data to the server using a POST request to the resource /recipes

Within the server code, all recipes will be stored in a single object called database. The keys of this object will be unique IDs and the values will be the recipes associated with those IDs. I'm stuck on a task where I'm supposed to add a route within the server code to handle POST requests to the /recipes resource. The handler for this route should:

1. Extract the recipe object included in the POST request body
2. Generate a unique ID for the new recipe (Etc. a basic integer that increases every time a recipe is added.)
3. Add a new entry into the recipes object with the key being the unique ID and the value being the recipe object.

When testing my code by adding a few recipes to my server, I should be able to just log the contents of the recipes object to see that it is storing the correct data, like in the picture below (this picture isn't mine):

load recipe in cmd

So as shown in the first picture of my screen, I filled in the contents of the recipe I want to add in create.html. When I click on the "Save Recipe" button however, instead of loading the contents of the recipe into my cmd window, I get the error:

I am getting a TypeError in this code

I created a dictionary that counts the number of occurrences of each word in a separate text file. So far it looks like this.
