How do I make a list of data frames?

How to Make a List of Data Frames 📋

So, you need to make a list of data frames and access each of those data frames from the list? No worries, I've got you covered! 😎

The Problem 🤔

Let's start by understanding the problem. You have multiple data frames (d1 and d2 in this case) and you want to store them in a list so that you can work with them more efficiently. Additionally, you want to be able to easily access each individual data frame from the list when needed.

The Solution 💡

To create a list of data frames, follow these steps:

1. First, let's create the data frames d1 and d2 as mentioned in the example:

d1 <- data.frame(y1 = c(1, 2, 3),
                 y2 = c(4, 5, 6))
d2 <- data.frame(y1 = c(3, 2, 1),
                 y2 = c(6, 5, 4))

1. Now, let's put these data frames in a list. To do that, use the list() function and pass the data frames as arguments:

myList <- list(d1, d2)

That's it! 🎉 You have successfully created a list (myList) containing the data frames d1 and d2. Each data frame is now an element of the list.

Accessing Data Frames from the List 📂

To access individual data frames from the list, you can use indexing. It's similar to accessing elements of a regular vector or list. Let's see how it works:

1. To access the first data frame (d1) from the list, use this syntax:

df1 <- myList[[1]]

The double brackets [[1]] indicate that we want to access the first element from the list.

1. Similarly, to access the second data frame (d2), use:

df2 <- myList[[2]]

Now, you can work with each data frame (df1 and df2 in this case) independently, perform operations, manipulate data, or whatever you need to do.
