YOU CAN SUPPORT ME HERE: 🤍 With just dplyr 10 commands at your fingertips, you can select, rename and create new columns (mutate), arrange or filter out rows, group rows together and then summarize those groups and be able to combine all these data wrangling techniques in a single pipeline like never before. And the best part? These commands are very easy to master, as most of them are common English verbs like “select” or “summarise”. These verbs will allow you to solve the vast majority of your data manipulation challenges. For more details and R code go to: 🤍 Enjoy! 🥳

Manipulating data with R is typically an important first step before other things like visualization and modeling can be done. And "dplyr" is an extremely useful package for beginners, which will quickly help you filter rows, arrange rows, select and rename columns, mutate the dataset to add new columns, created grouped summaries, and join to other datasets. Please note that code in this tutorial was adapted from Chapters 5 and 13 of the book "R for Data Science" by Hadley Wickham and Garrett Grolemund.

If you are learning to work with data then being able to structure, manipulate and summarize your data is extremely important. This forms part of what we call descriptive statistics. the group_by() and summarise() functions are part of the tidyverse set of packages. So if you're an aspiring data scientist or statistician, or you're doing a PHD or masters degree and need to be able to do quantitative analysis - then this video is for you.

This video is about how to recode data and manipulate data using R programming. It is really an R programming for beginners videos. It provides a demonstration of how to recode data using the tidyverse package (specifically the dplyr package in the tidyverse set of packages). The demonstration is in R Studio. This channel is for people who are interested in quantitative and statistical analysis using R. Everything to do with data science. This video is part of the "cleaning data" series.

Data cleaning is one of the more undervalued steps in a data anlaysis. In this episode we'll use a variety of functions from the tidyverse to get three data frames into the right format and then we'll join them all together. This will help us get ready for downstream analyses looking for microbiome-based biomarkers associated with colorectal cancer. In this episode, Pat will use the #tidyverse in #RStudio.

Joins let you combine two data tables together based on a shared column that uniquely identifies the records, also known as a key column. When your data is spread out across multiple tables, you may need to perform one or more joins to get it all into one big table before doing other data cleaning and analysis tasks.

In this video I'm showing you how to merge data frames with the dplyr package in R. The video includes six different join functions, i.e. inner_join, left_join, right_join, full_join, and anti_join. For each function, I show a reproducible example as well as a graphic, which illustrates how the data is merged. Also check out this tutorial on the join dplyr functions: 🤍 In this tutorial, you can find further examples, which are a bit more complex (e.g. merging multiple data frame or joining by multiple columns). Have fun with the video and let me know in the comments, if you have any feedback or questions.
The UQ Library presents a session on R data transformation with dplyr.

dplyr package is an exciting way to manipulate the data. It is an R package that provides you with a fast and intuitive way to transform data sets with R. dplyr is the successor of plyr and is mainly authored by Hadley Wickham and Romain Francois. It is designed to be intuitive and easy to learn, thereby making "doing things" in R more user-friendly. Basics dplyr tutorial introduces six key functions to you: summarize, group_by, select, mutate, filter, arrange. You will also learn how to use pipe operator to chain the functions - %＞% To stay up to date with our latest videos make sure to subscribe to this YouTube channel!
