What is data manipulation in r with the help of data structures we can represent data in the form of data analytics data manipulation in r can be carried out for further analysis and visualisation before we start playing with data in r you must learn how to import data in r and ways to export data from r to different external sources like sas spss text file or csv file. Data manipulation with r real world data is messy thats why packages like dplyr and datatable are so valuable using these packages you can take the pain out of data manipulation by extracting filtering and transforming your data clearing a path for quick and reliable data analysis. Data manipulation in r with dplyr package there are different ways to perform data manipulation in r such as using base r functions like subset with within etc packages like datatable ggplot2 reshape2 readr etc and different machine learning algorithms
