any inbuilt R function here to help out

[satyabansahoo2000]

I have the dataframe with some values that are only different in salary section and first column is id. so I want to group using id as well as find the mean of salary while keeping other attributes that contains similar values as it is. It's like squeezing the data by calculating the mean of salary.

id	name	salary	age
1	amit	5000	23
1	amit	8000	23
1	amit	5000	23
2	joseph	5600	22
2	joseph	4800	22
2	joseph	7000	22
3	nina	3600	24
3	nina	2500	24
3	nina	5000	24

Output I want :-

id	name	salary	age
1	amit	6000	23
2	joseph	5800	22
3	nina	3700	24

yourdata |> 
group_by(id,name,age)  |> 
summarise(salary = mean(salary))

Assuming that age is fixed for id; which seems like it might be in doubt unless age is never updated over time and so is only accurate to the initial entrance of an id.
