How to use transmute() to Change and Drop Variables In R Language
If you want to change the values of variables and simultaneously drop others, you can use transmute(). This function works similarly to mutate() but only keeps the variables that are explicitly mentioned.
# Change 'score' and keep only 'id' and 'score'
data <- data %>%
transmute(
id,
score = score * 1.2
)
# Display the updated data frame
print(data)
Output:
id score
1 1 129.36
2 2 134.64
3 3 118.80
4 4 121.44
5 5 151.80
