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

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

The best!!!

Error in `rename()`:
! Can't rename columns that don't exist.
✖ Column `mm` doesn't exist.
Backtrace:
1. gbdata2 %>% select(compliance_to_tt_in_mon) %>% ...
3. dplyr:::rename.data.frame(., compliance_to_tt_in_mo = mm)

Error in rename(., weight = mass) : unused argument (weight = mass)

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

man i just wanted to see how you put categories on first row in respective columns and adjacent data🤕

I'm really enjoying your videos. are you able to make a video on data merging?

Real smooth, thanks for keeping it simple and straight forward :)

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

THE BEST!!!

sw = starwars %>%
select(name,mass, height) %>%
rename( mass = weight) code did not change the starwars dataset mass to weight

I love this guy. Short, no BS, well-presented and approachable tips for programming dunces like me. Subscribed.

You have the best videos ! You make it fun and super duper easy 😂

Excellent .. thanks a lot

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?
