Hey guys, I am having a bit of trouble here.
I want to count the duplicated rows on my df.
a = c(1, 1, 1, 2, 2, 2, 3, 4, 4) b = c(3.5, 3.5, 2.5, 2.5,3, 2.5, 1, 2.2, 7) df <-data.frame(a,b) df #This was my 1st step, trying to understand the duplicate values, and then I would count them but... df %>% duplicate() #Nothing is happening and I keep the exact same values from df. it is like duplicate is doing nothing
So I want to know how many duplicates I have in my df.
Bonus questions: how to subset my duplicate values to another data frame?
Not sure if it is important but:
In my original Data Frame I have more columns
