Let's say I have a following very simple data frame:
a <- rep(5,30)
b <- rep(4,80)
d <- rep(7,55)
df <- data.frame(Column = c(a,b,d))
What would be the most generic way for removing all rows with the value that appear less then 60 times?
I know you could say "in this case it's just a", but in my real data there are many more frequencies, so I wouldn't want to specify them one by one.
I was thinking of writing a loop such that if length() of an 'i' is smaller than 60, these rows will be deleted, but perhaps you have other ideas. Thanks in advance.
