Introduction to R: Data Frames

Data Frames in R are data structures that store tabular data with rows and columns similar to an excel spreadsheet. Data Frames are among the most common data structures for working with data in R and many data reading functions load data into R in the form of data frames. They are analogous in many ways to the data frames provided by the pandas package in Python.

This is lesson 8 of a 30-part introduction to the R programming language for data analysis and predictive modeling. Link to the code notebook below:

This guide does not assume any prior exposure to R, programming or data science. It is intended for beginners with an interest in data science and those who might know other programming languages and would like to learn R.

I will create the videos for this guide such that you should be able to learn a lot just watching on YouTube, but to get the most out of the guide, it is recommended that you create a Kaggle account so that you can fork and edit each lesson so that you can follow along and run code yourself.

Thanks for your video. Did you say that data frame makes character vectors into factors (as an interger)? But I am getting character vector as character. Would you please make clear about the matter?

> typeof(df1$Conditions)
[1] "character"

at 12:27 it looks like its dropping columns not rows? if I'm not mistaken
