How to Import, Manipulate & Visualize Data Using the tidyverse in R | readr, dplyr & ggplot2 Package

This video demonstrates how to import, manipulate, and visualize data using the tidyverse in the R programming language. The video is part of a teaser series for the Statistics Globe online course on "Data Manipulation in R Using dplyr & the tidyverse". More info: statisticsglob...

Thank you so much Saima, looking forward to the start of the course! :)

[@dedisetiawan3245]

thank, how to change the first column to the name of the school? Thanks for the answer.

[@cansustatisticsglobe]

Hello, Sorry I couldn't get you very well. There is no school information in the dataset. Could you please give some more details? Best, Cansu

[@mayankpatel9379]

Can you please tell me how to add features in r studio my data is full of website in need to find is it malicious or benign

[@cansustatisticsglobe]

Hello! I am not sure if I got your questions very well. Do you want to add new variables/features to the imported dataset? Best, Cansu
