Bare with me... I am using the R/RStudio with the data mtcars, dplyr , mutate and the summarise commands. Also tried group by.
I want to center the values mtcars$mpg then take that info and display the summary of the number of cylinders vs centered mtcars$mpg.
So far...
mtcars %>% mutate(centered_mpg = mpg - mean(mpg, na.rm = TRUE)) %>% summarise(centered_mpg, cyl)
The above produces:
centered_mpg | cyl |
---|---|
0.909375 | 6 |
0.909375 | 6 |
2.709375 | 4 |
1.309375 | 6 |
... | ... |
