R programming for beginners: Rename variables and reorder columns. Data cleaning and manipulation.

This is an R programming for beginners video. Learn how to rename variables and reorder columns in R. If you want to use the Tidyverse in R to manipulate data and clean data then you need to start by using the select function to select and order your columns. Then you can use the rename function to change the names of variables. This is the first step in learning about data science and data analysis. Once your data is clean, you can use R to do quantitative analysis and statistical analysis.

Is there an easy way to rename 150 variables without writing in each variables old and new name?

[juanaguirre]

How do I save that rename? When I bring the data set back up it reverts back to its original names

[Maryjanesdreamland]

Do you have data sets available for us to download for practice?

I get an error "object not found" eventhough the variable appears in the header., so i´ve been unable to rename it. Any help? I already checked for misspelling

Quick question: When I renamed the mass column weight, the console showed a change in the name but the actual graph still remains as mass. How do I fix that?

✖ Column `mm` doesn't exist.

Hello i imported an excel sheet and the name of the column is an entire question. How can i rename it?

Handy tip for anyone following: If you want to rename AFTER you have already renamed, you need to put the changed variable name into the select() field so it retrieves the new variable that can then be renamed for a second time.

starwars_mod <- starwars %>% #storing the starwars dataframe into new dataframe called starwars_mod
select(sex, mass, height, species, everything()) %>% #orders specified columns and puts all everything else after.
rename(gender_true = sex) #changing variable name from "sex" to "gender_true"

Second renaming code
starwars_mod <- starwars %>% #storing the starwars dataframe into new dataframe called starwars_mod
select(sex, mass, height, species, everything()) %>% #NOTE that variable sex must be renamed to the new variable name gender_true
rename(gender_2ndRename = gender_true) #changing the renamed variable again but to "gender_2ndRename"

Hi is the pipe operator can be used only with tidy verse package? Or we can use it in any other data?
